I am attempting to run a remote control car via the raspberry pi. I setup a L239D chip circuit following this guide. http://computers.tutsplus.com/tutorials/controlling-dc-motors-using-python-with-a-raspberry-pi--cms-20051 I then attempted to run the code, which resulted in a whole lot of nothing. I started checking the numerous pin voltages, etc. and I noticed that the GPIO 3 pin (using physical pin numbering) was high even without running any code. I rebooted the pi and checked the pin again and it was still high. I ran a code that basically set the pin to False and it turned the pin off but as soon as the code was done running it went high again. I have tried GPIO.cleanup() to no avail. My motor voltage is 7 volts, and my pi is just running from a 5v litium battery. I am really hoping that it is just a setting issue and I haven't permanently broken the pi. Any help would be appreciated!!
