hi,
im Ian Jakubek and im new to arduino.
The problem i have is that when i run the code below on my arduino uno with arduino uno rev3 motorshield i get the motors to move but i also get a loud beeping noise.
this makes me worried, so can anyone help me with this.
the code:
/*************************************************************
Motor Shield 2-Channel DC Motor Demo
by Randy Sarafan
For more information see:

*************************************************************/
void setup() {
//Setup Channel A
pinMode(12, OUTPUT); //Initiates Motor Channel A pin
pinMode(9, OUTPUT); //Initiates Brake Channel A pin
//Setup Channel B
pinMode(13, OUTPUT); //Initiates Motor Channel A pin
pinMode(8, OUTPUT); //Initiates Brake Channel A pin
}
void loop(){
//Motor A 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
//Motor B backward @ half speed
digitalWrite(13, HIGH); //Establishes backward direction of Channel B
digitalWrite(8, LOW); //Disengage the Brake for Channel B
analogWrite(11, 255); //Spins the motor on Channel B at half speed
delay(3600);
digitalWrite(9, HIGH); //Engage the Brake for Channel A
digitalWrite(9, HIGH); //Engage the Brake for Channel B
delay(1000);
}
thx,
