User questions & answers

Question:	Could this module be used for a 12v 80ma no-load current motor? i don't think the regular l298n 2a module will supply the current needed
Answer:	The real question is what is the current draw when your motor is under load, because that’s when current will spike. Make sure that is safely below 7A. 80mA would be no problem.
Question:	The manufacturer says it needs, requires, must have a heat sink. so why did anyone manufacture it without a component that it absolutely needs
Answer:	I have used this board with and without heatsinks to drive NEMA 23 stepper motors at 1.5-2A, and haven't any significant heating in either case.
Question:	How am I supposed to have a separate ground for the motor with a single PS
Answer:	The polarity of the single power supply applied to the motor through the DROK is reversed by the DROK to reverse the direction of the motor if so controlled by the DROK. If the motor shares a common ground with the single power supply, there will be a short circuit through the DROK when the motor is commanded in the reverse direction. It is critical that neither motor power lead is referenced to the single power supply applied to the DROK input.
Question:	Can this be used to slowly increase the voltage in a power wheels type car? Wanting to increase voltage over time from 12-24v
Answer:	You can increase the average voltage overtime. Basically you need a 24V supply. And then you can pwm from 50% to 100% of whatever the range is.

Control Stepper Motor by IR

In this project, you will learn a fun and easy way to control a stepper motor from a distance using an IR remote control.

The 28BYJ-48 is a small 5 volt geared stepping motors which are apparently widely used to control things like automated blinds, A/C units. And it come with a ULN2003 stepper motor driver board, allows you to easily control the 28BYJ-48 stepper motor from a microcontroller.

The IR sensor is connected to the microcontroller board directly since it uses almost no power.When you are fully connected, you can control the stepping motor through IR remote.

DC Motor with L293D and Relay

In this project you will learn how to control a small DC motor by microcontroller board with using a L293D transistor and Relay.

L293D transistor is a very practical chip that can independently control two DC motors. In this experiment, just half of the chip is used. Since most pins on the right side of the chip are used to control the second motor, they will not be used here.

Relays are generally used to switch smaller currents in a control circuit and do not usually control power consuming devices except for small motors and Solenoids that draw low amps. Nonetheless, relays can "control" larger voltages and amperes by having an amplifying effect because a small voltage applied to a relays coil can result in a large voltage being switched by the contacts.

User questions & answers

Question:	Is there a way for me to detect a stall using this driver
Answer:	No, there is no feedback from the motor to the driver. Possibly monitor the current used by the motor with a Hall Effect transducer and, if it exceeds a certain value, consider it stalled.
Question:	I lose the voltage from 10v to 4.5v, as soon as I connect to motor controller. Any idea why it is happening and how to correct it
Answer:	I need a bit of context for your question. are you using a microcontroller with the L298? How many motors are you using? do you have a separate power supply for said source of controls? Are you using an arduino?
Question:	Can you use this with the Arduino Stepper.h library to run a 5V stepper motor? When I use it at the full 12V it heats up my motor like crazy
Answer:	5V is the limit. 12V will burn up the motor.
Question:	What are those blue connectors for? Can I see a connecting diagram or instructions of some sort
Answer:	The blue terminal blocks are for power connections. The 3-term block is for supply voltage, ground, and +5V out from on-board regulator. Each 2-term block is for a power circuit to a motor (voltage is same as supply). A search online for "l298n driver module" images gives a lot of useful connection diagrams. ST Microelectronics provides good technical documentation for the L298 IC, itself, which describes the power limitations.

Soil Moisture Sensor Module

In this project, you will understand how you can use the soil moisture sensor in your projects. The soil moisture sensor or the hygrometer is usually used to detect the humidity of the soil. So, it is perfect to build an automatic watering system or to monitor the soil moisture of your plants. The voltage that the sensor outputs changes accordingly to the water content in the soil.When the soil is:

• Wet: the output voltage decreases
• Dry: the output voltage increases

Introduction

Application

The Joystick module is usually used to be applied to convenient control of objects (like a two-degree of freedom servo mount) to move in a two-dimensional space. With power light and indicator of digital signal output. It can be used in the remote controller for many robot projects



Component List

- 1 x Joystick PS2 module

- 1 x 5-Pin anti-reverse jumper wire

• Works with Arduino and Raspberry Pi
• Game joystick PS2 module suits for Arduino PS2 , connects to two analog outputs, the robot is at your commands with X,Y control, and one of digital output (Z).
• The cross rocker is a bidirectional 10k resistor; its resistance changes with different directions. Push the joystick towards different directions and the voltage read increases or decreases
• Press it down, then the output is low level and the corresponding LED lights up; otherwise it stays off.

Answer:	Dear sir, We are sorry to tell you that we have not black on white color LCD now. If you have any issues about the product, please feel free to let us know and we will try our best to solve it. Best regards, Linda from Arducam Support Team
Question:	Title says that it is for arduino and raspberry pi pico. but pico uses 3v and this unit uses 5v. is it compatible? can it be used with pico
Answer:	You need a level shifter like https://www.amazon.com/gp/product/B074M8TM81 That lcd module uses about 6 or 8 lines so you would need to use 2 or three of this type level shifter.
Question:	I am unable to write to the second line. I think it shoud start at 40. Does it
Answer:	Perhaps, you can add a 0x40 to the 2nd line, you can refer to the next code.#include #define uchar unsigned char #define uint unsigned int sbit lcden=P3^2; //enable com sbit lcdrs=P3^0; //Data command options sbit rw=P3^1; uchar code table="xian shi 1"; //Type the charactersuchar code table1="xian shi 2"; //Type the charactersuchar num=0; void delay(uint z) { uint x,y; for(x=z;x>0;x--) for(y=110;y>0;y--); } void write_com(uchar com)//According to the sequence diagram write instruction program{ lcdrs=0; rw=0; P1=com; delay(5); lcden=1; delay(5); lcden=0; } void write_data(uchar date)//According to the sequence diagram write data program{ lcdrs=1; rw=0; P1=date; delay(5); lcden=1; delay(5); lcden=0; } void init() { lcden=0; //Can make the low level write_com(0x38); /*Display mode setting 00111000 set 16 * 2 5 * 7 lattice 8 bits of data interface*/ write_com(0x0f); /*Display switch and the cursor 00001 DCB Settings D = 1, open display D = 0, turn off the display C = 1, display the cursor C = 0, do not display the cursor B = 1, the cursor blink B = 0, the cursor is not flashing*/ write_com(0x06);//Address pointer + 1 + 1, and the cursor automatically write character screen do not move write_com(0X01); write_com(0X80); } void main() { init(); for(num=0;num { write_data(tablenum); delay(50); } write_com(0X80+0x40); for(num=0;num { write_data(table1num); delay(50); } while(1); } For more information, please visit: http://www.uctronics.com/Amazon/Arducam_C0048_1602.pdf
Question:	Where can I find a bezel/faceplate to fit this display? I want to snap it onto the perimeter to finish my project
Answer:	I found some plastic face plates that were apparently die cut for this size display. They are designed to be bolted or glued over the panel opening housing the display. If I remember correctly, they are available in different colors and sizes. I bought a dozen of them and I am happy with the results. They do not snap onto the perimeter of the display. I found them by Google searching the internet. I wish I could give you the URL but do not have it handy.
