User questions & answers

Question:	will these work with raspberry pi
Answer:	Yes, running 90 fps at 4K for UHD gaming
Question:	What's the AWG
Answer:	You can use it with X299 chipset motherboard with LGA 2066 However, since the power consumption is large, I think that the original performance can not be demonstrated unless it is a good thing around the power supply
Question:	Can you cut the wire and solder it to something like a hardware on/off switch and still keep the connector on one end
Answer:	These are some awesome answers. Yes ram is the answer. However, you could run 18 processes in parallel. Or 18 vm s really slowly.
Question:	Can you take off the ends and cut the wires and then put the ends back on
Answer:	Minecraft is mainly CPU based. This would be a great processor to choose if you choose to fill the whole world with TNT and watch it blow up with 60 FPS.

The most complete starter Kit with high quality components and sensors

Quantity and quality are both important here in Elegoo MEGA 2560 starter kit. The most essential parts in this kit are MEGA 2560 controller board and expansion board, which is a perfect clone with excellent product finish Compatible with Arduino projects. Besides, we offer other over 60 kinds of components and sensors from small parts like LED diodes, resistors and potentiometer to big parts like LCD1602, RFID module and 830 tie-points breadboard, which meet your demands for your different projects either it is simple or complex.

Sturdy quality is definitely the most important thing to Elegoo even with so many components provided we never compromised on the quality. Instead we keep improving our product quality in our own factory and we produce the products by ourselves under high standards and strict quality control. Pins and wires on some of the parts like LCD16502 and motors have been pre-soldered which is very convenient and saves your time.

LCD1602 Display module

LCD1602 module is a display that has an LED backlight and can display two rows with up to 16 characters on each row. You can see the rectangles for each character on the display and the pixels that make up each character. The display is just white on blue and is intended for showing text.

Lining up the display with the top of the breadboard helps to identify its pins without too much counting, especially if the breadboard has its rows numbered with row 1 as the top row of the board. Do not forget, the long yellow lead that links the slider of the pot to pin 3 of the display. The 'pot' is used to control the contrast of the display.

DC Motors and L293D Transistor

In this project you will learn how to control a small DC motor using a Mega2560 board and a L293D transistor, which is a very useful chip. It can actually control two motors independently. We are just using half the chip in this lesson, most of the pins on the right hand side of the chip are for controlling a second motor.

L293D is quadruple high-current half-H drivers and designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. The L293D is also designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V and drive inductive loads such as relays, solenoids, dc and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.

74HC595 Shift Register and LEDs

74HC595 is a Serial to Parallel Converter which has eight outputs (perfect) and three inputs that you use to feed data into it a bit at a time.

This chip makes it a little slower to drive the LEDs (you can only change the LEDs about 500,000 times a second instead of 8,000,000 a second) but it's still really fast, way faster than humans can detect, so it's worth it!

74HC595 shift register is a type of chip that holds what can be thought of as eight memory locations, each of which can either be a 1 or a 0. To set each of these values on or off, we feed in the data using the 'Data' and 'Clock' pins of the chip.

Compatibility with Official Arduino IDE, Software, Sendsors and Codes

Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board.

For the reason of open source, the manufacture of Arduino boards and software distribution by anyone is permitted. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.

Elegoo is one of the manufacturer on the market, whose clone products are compatible with the official Arduinomicrocontroller boards, they can use the official Arduino software, sensors and codes.

Learn Electronics and Programming with ELEGOO

The UNO boards can be used as the brains behind almost any electronics project. UNO can interact with buttons, LEDs, motors, speakers, GPS units, cameras, the internet, and even your smart-phone or your TV! By connecting the UNO board with a personal computer via a USB cable and uploading programs to the board, users can create digital devices and interactive objects that can sense and control objects in the physical and digital world like robots or even honest fortune-telling machines.

For this Elegoo Super Starter Kit, we provide a 24-lesson tutorial, introducing the basic setting of the software IDE, the working principles of the sensors and the simple program to enable the UNO board to control the sensors.

This Kit is suitable for 10-year-old and up. Younger kids should be under supervision and guidance of adults.

74HC595 and LEDs

74HC595 is a Serial to Parallel Converter which has eight outputs (perfect) and three inputs that you use to feed data into it a bit at a time.

This chip makes it a little slower to drive the LEDs (you can only change the LEDs about 500,000 times a second instead of 8,000,000 a second) but it's still really fast, way faster than humans can detect, so it's worth it.

4 digit 7 segment display

7 segment displays consist of 7 LEDs, called segments, arranged in the shape of an “8”. Most 7-segment displays actually have 8 segments, with a dot on the right side of the digit that serves as a decimal point. When using 4-digit 7-segment display, the common anode or common cathode pin is used to control which digit is displayed. Even though there is only one digit working, the principle of Persistence of Vision enables you to see all numbers displayed because each the scanning speed is so fast that you hardly notice the intervals. By building the circuit and editing the program, users can make a simple display showing certain numbers, or more complexly, a count-up timer or a elecrical rolling dice.

Stepper Motor

Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called "phases". By energizing each phase in sequence, the motor will rotate, one step at a time.

With a computer controlled stepping you can achieve very precise positioning and/or speed control. For this reason, stepper motors are the motor of choice for many precision motion control applications.

the simplest way of interfacing a unipolar stepper motor to UNO board is to use a breakout

for ULN2003A transistor array chip, applying voltage to each of the coils in a specific sequence.

User questions & answers

Question:	Ordered two of these and get the same error message: avrdude: ser_open() : can't open device "\\.\COM4": the system cannot find the file specified
Answer:	18 abd 20 awg work
Question:	is the Elegoo compatible with the official Arduino program? (1.8.1 to be exact
Answer:	Yes, I have done that and it works like any ordinary wire. But it’s important to know that you cannot really put the crimped connector ends back onto the wire after removing. (You can but it’s not made to do so)
Question:	Does this use the CH
Answer:	If you are talking about taking off the black dupont connector and sliding the pinned wire into a new dupont connector, then yes, you can. Each connector has the tab that you would expect in a dupont connector. I just did this to 4 wires putting them into a 4 pin connector. If you want to cut the wires shorter then you will need the dupont pins, a wire stripper, and a crimper to crimp the new pins onto the shortened wires. Sorry this answer is long past when it is likely useful to you, but it may help others.
Question:	Is this the same thing as an arduino
Answer:	Most definitely

User questions & answers

Question:	Is there an available pdf version of the cd-rom
Answer:	This fingerprint scanner needs a micro controller with a firmware that can operate the fingerprints that are scanned and stored in the device. It works with a 3.3 to 6V DC power supply and the digital interface to the micro controller requires 3.3V to 5V. If you run it off a 9V battery, you will need a voltage regulator to power this fingerprint scanner as well as the micro controller.
Question:	ok for 8yr old
Answer:	Yes it is. However, you must buy the cable TTL Serial, this is crucial for establishing the connection with your arduino.
Question:	Are the data/specification sheets for the sensors provided
Answer:	The device works with power from 3.3V to 6V. It should work fine with 3.3V Raspberry Pi signals. Make sure you power the fingerprint module with the same 3.3V DC

The dedicated digital modules collection technology and the temperature and humidity sensing technology are applied to ensure that the product has high reliability and excellent long-term stability. The sensor includes a resistive sense of wet components and a NTC temperature measurement devices, and connects with a high-performance 8-bit microcontroller.

HC-SR501 PIR Motion Sensor

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. PIRs are basically made of a pyroelectric sensor, which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted.

GY-521 Triaxial acceleration triaxial gyroscope sensor

GY-521 six-axis sensor usually consists of two which are accelerometer and gyroscope. The GY-521 is a 6 DOF (Degrees of Freedom) or a six axis IMU sensor, which means that it gives six values as output. Three values from the accelerometer and three from the gyroscope. It is also a sensor based on MEMS (Micro Electro Mechanical Systems) technology. Both the accelerometer and the gyroscope is embedded inside a single chip. This chip uses I2C (Inter Integrated Circuit) protocol for communication.

User questions & answers

Question:	Is the output voltage regulated? In other words will it maintain a stable 12V output
Answer:	Dear Ilya,Thanks for your question.Output voltage of this battery is not regulated.Output voltage range of the battery is from 12.6v to 9.0v. It's workable for most 12v application such as led strip,amplifier,heat products...etc.Best Regards
Question:	Does this battery have protection to prevent over charging and under charging
Answer:	Dear Mark,Thanks for your question.There are over charge / over discharge protection circuit inside our battery.And there is overcharge protect circuit inside our AC-DC charger. So don't worry about overcharge/overdischarge .Best Regards
Question:	Can I use car cigaret socket to charge this battery pack
Answer:	Please Note - you cannot just plug it into a cigarette lighter to charge the battery pack. It requires a regulated 12.60 volt power supply. If you exceed this voltage you WILL damage the battery pack. Lithium-ion ICR cells do not tolerate over voltage charging above 4.2 volts per cell and will overheat and vent. The cells in these battery packs are not IC protected cells. These battery packs consist of 6 Samsung ICR1860 cells in a parallel series configuration and they do work great but To charge it from your vehicle or any other source you will need a 12.60 volt regulated output power supply. Caution- Warning..... Please be careful! I work with lithium-ion battery packs all the time. Under certain conditions you can create a fire so be careful! As an additional note- this pack is falsely advertised as a 6000mah pack - it is actually a 5400mah pack as the cells are Samsung ICR18650- 2700mah cells in parallel.
Question:	what is the max power draw for a 5v device? Can it deliver 3 or 4 Amps
Answer:	Dear Benoit,Thanks for your question.Max. power draw of our battery is 2A @ 5v and 3A @ 12v.Best Regards,

User questions & answers

Question:	what is the max volts/watts/current that can be passed through the board
Answer:	As long as your bed frame has holes in it this headboard should work. It has several different holes, so you can customize how high or low the padded back is. I have mine attached to a basic Hollywood frame. It does NOT come with the screws to attach it though. You will have to supply those.
Question:	Can you cut the boards apart? That is, one board cut into 3 pieces for three independent projects
Answer:	I attached the headboard directly to the wall. Looks great!
Question:	Will M2 size standoffs fit in these mounting holes? They measure very close to 2mm
Answer:	No. For mine, I bought 4 sets of bolt, nut and washer from Home depot. Carriage bolt 5/6 x 1-1/2. Code AHA. Nut: ABC, washer: ABB.
Question:	Are electrical connections made between holes in a pattern similar to those on a solderless breadboard? Or is each hole electrically isolated
Answer:	I have no idea, but we have had this bed frame for 2 months, it is in my daughters room , she weighs 30lbs, and I or my husband sleep in the bed with her so 230lbs it holds. Both my kids jump on it all the time and it has held up great!
