Analog PWM for servomotor

193

02:18:04

This circuit will allow you to control a servo with any analog signal. As long as the input (green node) is between 0.25 and 0.5 volts(using the 5v battery as reference, for the virtual ground configuration between -2.25 and -2volts), the servo will move.

I haven't tried the circuit myself, but once I have some time to spare, I'll build it.

I got the input calculations wrong, sorry. I'll check them later

The calculations are correct now I believe. Please check the description for details
