The tests shown on this tutorial were performed using an ESP32 board from DFRobot. With end stops and wall push button to open and close. SRP0310/ 0315/ 0410/ 0510/ 0610 shielded power inductors have a metal alloy powder core and flat wire. Introducing the Relay Module. Even a small 5V DC Motor draws a high initial current of around 300 – 400 mA. int y; When done uploading the code into my arduino UNO, the LCD display nothing.   digitalWrite(2,HIGH); If you use a relay to control your motor, you would not be able to control it with the PWM signal. Though, the Arduino motor program uses the basic built-in functions such as digitalWrite() and analogWrite(). Control DC Motors with L293D Motor Driver IC & Arduino . They recieved a HIGH/LOW voltage from the Arduino. Relays responses will be too slow for such applications. I modified this code to control two relays which are wired to motor poles for Forward or Reverse movements until they physically reach a limit switch on either side. Now the voltage between the wiper terminal of potentiometer and Gnd determines the PWM voltage at pin no 6 and as wiper terminal is rotated, voltage at analog pin A0 changes causing change in speed of motor. The arduino will use a 5volt relay to switch the motor on and off. In this example, we will show how to control the direction and speed of a small-sized direct current (DC) motor) by using the driver chip L293D and the Arduino board. Thanks.
