Motor Shield H-Bridge L293NE PUBLIC

This circuit is available on Arduino playground. If you have doughts you can consult the link: http://itp.nyu.edu/physcomp/Labs/DCMotorControl

Here is the code to program the arduino to test this circuit:

//DC Motor With H-Bridge L293NE or SN754410 //----------------------------------------- // //Author: Pedro Martins // pin 3: Motor Logical pin 2 // pin 4: Motor Logical pin 1 // pin 9: Enable H-bridge //-----------------------------------------

const int motor1Pin = 3; const int motor2Pin = 4; const int enablePin = 9; //----------------------------------------

void setup() { // set all the other pins you're using as outputs: pinMode(motor1Pin, OUTPUT); pinMode(motor2Pin, OUTPUT); pinMode(enablePin, OUTPUT);

// set enablePin high so that motor can turn on: digitalWrite(enablePin, HIGH);

}

void loop() { //move motor foward digitalWrite(motor1Pin, LOW); digitalWrite(motor2Pin, HIGH); delay(3600); //move motor backward digitalWrite(motor2Pin, LOW); digitalWrite(motor1Pin, HIGH); delay(3600); }

You can also use H-bridge by Toshiba SN754410.
