Controlling a DC Motor speed by BARRAGAN Demonstrates the use a DC Motor motor with the L293D Motor Driver chip. int motorPin = 37; // L293D Pin En1 connected to pin PWM 37 void setup() { pinMode(37, OUTPUT); } void loop() { analogWrite(motorPin, 512); // turn ON the Motor at medium speed delay(100); } Wiring is an open project initiated by Hernando Barragán. It is developed by a small team of volunteers. © Info, Processing © Info
