I have tried adapting the blink without delay code in Arduino examples with the h-bridge code I am using which is as follows
[const int switchPin = 2; // switch input
const int motor1Pin = 3; // H-bridge leg 1 (pin 2, 1A)
const int motor2Pin = 4; // H-bridge leg 2 (pin 7, 2A)
const int enablePin = 9; // H-bridge enable pin
const int motor3Pin = 5; //H-bridge leg 1
const int motor4Pin = 6; // H-Bridge leg 2
const int enablePin1 = 8;
void setup() {
// set the switch as an input:
pinMode(switchPin, INPUT);
// set all the other pins you're using as outputs:
pinMode(motor1Pin, OUTPUT);
pinMode(motor2Pin, OUTPUT);
pinMode(enablePin, OUTPUT);
pinMode (motor3Pin, OUTPUT);
pinMode(motor4Pin, OUTPUT);
pinMode(enablePin1, OUTPUT);
// set enablePin high so that motor can turn on:
digitalWrite(enablePin, HIGH);
digitalWrite(enablePin1, HIGH);
}
void loop() {
// if the switch is high, motor will turn on one direction:
if (digitalRead(switchPin) == HIGH) {
digitalWrite(motor1Pin, LOW); // set leg 1 of the H-bridge low
digitalWrite(motor2Pin, HIGH); // set leg 2 of the H-bridge high
digitalWrite(motor3Pin, LOW);
digitalWrite(motor4Pin, HIGH);
}
// if the switch is low, motor will turn in the other direction:
else {
digitalWrite(motor1Pin, HIGH); // set leg 1 of the H-bridge high
digitalWrite(motor2Pin, LOW); // set leg 2 of the H-bridge low
digitalWrite(motor3Pin, HIGH);
digitalWrite(motor4Pin, LOW);
}
