The second sketch is an attempt to add in servo functions.
The kicker is the Rover_Motors.ino runs the motors as I'd like them to, and I can control them on the serial port, and the Rover_Servos_n_Motors.ino controls the servos as I would like them to.
BUT The motors do not function in the sketch with the servos. As I'm extremely new to arduino code I was wondering if anyone spots and reasons why the motors will not drive when the servo code is inserted into the sketch?
On boards other than the Mega, use of the servo library disables analogWrite() (PWM) functionality on pins 9 and 10, whether or not there is a Servo on those pins. That is most likely the root of your problem.
You will need to use pins other than 9 and 10 for speed control of the motors or use an alternative servo library that does not use the same timer as PWM. There is a servo library called ServoTimer2 which does not interfere with PWM on pins 9 and 10.
Incidentally, why have you got the pinMode() commands in loop() ? The pin mode only needs to be set once in setup() and what is the purpose of while(1) when the loop() function does as its name suggests and loops ?
Wow thanks for the quick response! I will look into this and hopefully post back tomorrow if it was a success or failure haha.
The PinMode in loop() I originally had it only set it once, but I tried placing it in loop() just to see if it made a difference in getting the motors working (with little to no hope I was just out of ideas at that point lol). I just forgot to put it back. Thanks for the information on that as well though! I feel like such a novice at all this I really appreciate the help!
It is a very common problem and I nearly didn't bother to download your program but when I did I spotted the other things that I commented on, including the while(1)
