I was only planning to use the 9v battery to run the Atmega328 and sensors. The sensors and Xbee only use 56ma at 3.3V.
Since I cannot use pins 9 and 10, can I then have one servo on the left side controlled by an analog pin and another one on the left side with a PWM pin or will they get out of sync? To clarify can different servos on the same side of the drive train get their signal from a mix of analog and PWM pins?
Any thoughts toward signal noise? Thanks.
