I found this code for using one DC motor but the motor did not work. I got this error : avrdude: stk500_getsync(): not in sync: resp=0x00
How can I fix this code ?
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, 128); //Spins the motor on Channel A at full speed
delay(3000);
digitalWrite(9, HIGH); //Eengage the Brake for Channel A
delay(1000);
//backward @ half speed
digitalWrite(12, LOW); //Establishes backward direction of Channel A
digitalWrite(9, LOW); //Disengage the Brake for Channel A
analogWrite(3, 123); //Spins the motor on Channel A at half speed
delay(3000);
digitalWrite(9, HIGH); //Eengage the Brake for Channel A
delay(1000);
