Abstract:A 32-tap, linear-taper digital potentiometer acts as a variable resistor in a voltage divider, connected to the DIM input of
an LED driver (operating as a PWM driver for the solenoid). The circuit drives solenoids ranging from 6V DC up to 40V DC, using
only the solenoid's 6V to 40V DC source.
