Jon Garich - 3V DC Motor Code

//1.5-3.0 V DC Motor (Radioshack) Code

int switchPin = 2; // switch input
int motor1Pin1 = 3; // pin 2 on L293D
int motor1Pin2 = 4; // pin 7 on L293D
int enablePin = 9; // pin 1 on L293D
void setup() {
   // set the switch as an input:
   pinMode(switchPin, INPUT); 
   // set all the other pins you're using as outputs:
   pinMode(motor1Pin1, OUTPUT);
   pinMode(motor1Pin2, OUTPUT);
   pinMode(enablePin, OUTPUT);
   // set enablePin high so that motor can turn on:
   digitalWrite(enablePin, HIGH);
}
void loop() {
   // if the switch is high, motor will turn on one direction:
   if (digitalRead(switchPin) == HIGH) {
      digitalWrite(motor1Pin1, LOW); // set pin 2 on L293D low
      digitalWrite(motor1Pin2, HIGH); // set pin 7 on L293D high
   }
   // if the switch is low, motor will turn in the opposite direction:
   else {
      digitalWrite(motor1Pin1, HIGH); // set pin 2 on L293D high
      digitalWrite(motor1Pin2, LOW); // set pin 7 on L293D low
   }
