Tell us about yourself!
Hi thanks for tutorial!Sadly, I have no success in running my motors.I am confused about these lines with their comments:const int motorA1 = 5; // Pin 2 of L293const int motorA2 = 6; // Pin 7 of L293const int motorB1 = 10; // Pin 10 of L293const int motorB2 = 9; // Pin 14 of L293So which is right? the commented pins or the ones noted down (5,6,10,9). The choice of pins confuses me in terms of what they represent. Pin 9 in L293D is power to Driver - why is it connected to the motor?Help would be greatly appreciated!
