Hi fellows, I'm using an 12 volts and 35 ohms electomagnet.Using Gammon's circuit below.I've set pwm 30Hz to get a precise control(To make big duty cycle control).Because of the PWM's On/Off cycle electromagnet vibrating so much and its very noisy.I want to smooth PWM to analog so there will be no …
