I made a very simple buggy: https://projects.raspberrypi.org/en/pro ... ld-a-buggy
I made it the first time, wrote a python program, success.
I bough a new chassis and reused all of the hardware from the first buggy to make a new buggy with that chassis: failure
When I plug in only the left motor it runs as the program says, but when I plug in the right motor too both motors make a tiny and short noise as if they were trying to move but do not have enough power. I tried with another motor and the same thing happens. The batteries have only been used a for a total of around 8 minutes. Does anyone know why the second motor barely moves and makes the other motor barely move along with it?
