How to control an inverting amplifier using Arduino and a digital potentiometer.
An inverting amplifier is a differential amplifier in which that circuit's non-inverting input is grounded, and inverting input is identified with Vinput. An inverting amplifier The closed-loop gain is R2 / R1, hence Voutput = - R2/R1 Vinput so Voutput/Vinp...
