This project is an analog PWM servo control. It details the design of an op-amp based, analog oscillator that can produce hobby servo control signals based on any analog input (be it a potentiometer, DAQ card, or something else). Check details on the link below.

The author is using two TL072 dual opamps instead of a TL074 quad opamp. I don’t know why.
He is using a supply of only 5V when the TL072 and TL074 have a minimum supply of 7V. I don’t know why.
