WebNov 15, 2016 · Well, the tone is a square wave with frequency 100Hz, so every 5ms it will switch from Vdd to GND. If instead of using a fixed voltage you are using a PWM, you just have to turn it on and off. Be careful, though, that analogWrite is outputting a PWM wave, i.e. a square wave of frequency about 500 or 1000 Hz, not a fixed value. the party spot vineland nj
