I have an old motor shield but can see the revision 3 is still being sold: https://store.arduino.cc/arduino-motor-shield-rev3
When I follow the link for "Getting Started section" the page lists a lot of shields but not the motor shield. I must be missing something really obviously but I can't find a library for the motor board.
I'm trying to drive 2 DC motors.
From Chrisl's comment: https://github.com/gallingern/arduino-motor-shield-r3
You don't really need a library though as the code is simple enough:
void setup() {
//Setup Channel A
pinMode(12, OUTPUT); //Initiates Motor Channel A pin
pinMode(9, OUTPUT); //Initiates Brake Channel A pin
}
void loop(){
//forward @ full speed
digitalWrite(12, HIGH); //Establishes forward direction of Channel A
digitalWrite(9, LOW); //Disengage the Brake for Channel A
analogWrite(3, 255); //Spins the motor on Channel A at full speed
delay(3000);
digitalWrite(9, HIGH); //Engage the Brake for Channel A
}
