What about the voltage regulator? Is it heating up after a bit and dropping out?.
A schematic might help.

I think this is likely, are you running the motor's power through the regulator?Originally Posted by mackrackit

the motor does not have a voltage regulator, and i am running everything off of 4 AAA batteries. should i add a voltage reg? how will this affect my battey life?

Button cells ???
No need to see further ...

certainly the answer is " RTFM " or " RTFDataSheet " !!!

Are the batteries rechargeable? The total voltage could be with fully charged cells 4.8 to 6 volts nominal. One could be a bit low if you are running at 10MHz or above and the other is a bit high.
The 4.8 v will be fine if nothing causes to much of a voltage drop. The batteries may seem fine after everything stops due to rebound. Try a voltmeter when it is running to monitor the voltage to see for your self.
Solution might be to have a separate set of batteries for the PIC and another for the motors. Share the zero rail.
If you are not running rechargables then a regulator is recommended for the PIC. Keep the voltage at 5 volts or less here. If you run the PIC at 4 MHZ or so the voltage can be much lower, check the data sheet under electrical characteristics. A low drop out regulator may also be handy. If the batteries are max voltage 4.8 and you run at 4 MHz then you will not need the regulator.

Hi,Dave
The internal resistance of those batteries is FAR too high to power a servo , so a servo and a Motor ...
Want some values ??? just to laugh a bit ...
running the PIC @ 3 v could be a solution ... for the Pic only !!!

eYup, I was not really thinking about the motors, more to the PIC browning out. Good point.

No, I thought if you were, then you might be overloading it. Alain is one of this forums R/C and Servo EXPERTS, I would defer to his expertise.
