![]() ![]() Note that you can run both motors by sending characters as per your requirements.Įxample 2: Run Motor_1 & Motor_2 simultaneously in forward, then backward, and stop both motors. Similarly, you can also control Motor_2 by sending the above characters in the Upper case. Serial.println("Motor_1 and Motor_2 Stop") įirst I have define the variables for Arduino UNO pins as per connections and other variables for storing serial data and speed value. Serial.println("Motor_1 and Motor_2 Backward Direction") Serial.println("Motor_1 and Motor_2 Forward Direction") Serial.println("Minimum Speed Limit Reached for Motor_2: ") Serial.println("Motor_2 reduced Speed value: ") Serial.println("Minimum Speed Limit Reached for Motor_1: ") Serial.println("Motor_1 reduced Speed value: ") Serial.println("Motor_2 Backward Direction") Serial.println("Motor_1 Backward Direction") Serial.println("Motor_2 Forward Direction") Serial.println("Motor_1 Forward Direction") You can copy the code by clicking on the button in the top right corner of the code field and uploading it to your Arduino UNO board. It can provide a bidirectional drive current up to 1 A at voltages from 4.5 V to 36 V. The L293D is a quadruple high current half-H driver IC suitable for controlling DC motors. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to products on. Supplies Hardware components Arduino Uno Rev3 I have included a wiring diagram and details of Arduino code to control the DC motor by sending characters from Serial Monitor of Arduino IDE with multiple examples. Encoder 1 is located on the upper row of encoder port.In this tutorial, I will give you all the necessary information about controlling the speed and direction of a DC motor with an L293D motor driver IC using an Arduino UNO board.Encoder 1 - 1B B phase - Encoder of DC motor.Encoder 1 - 1A A phase - Encoder of DC motor.Encoder 1 - GND GND - Encoder of DC motor.Encoder 1 - 5V Vcc - Encoder of DC motor.(Optional) Connect the encoder port of DC motor controller to encoder pin of DC motor as follows:. ![]()
