Note that if your PWM signal has a maximum voltage of 3.3V for whatever reason (perhaps by running a 3.3V Arduino), the red wire should also be at 3.3V. Plug in the PWM wire to the Victor 888. Plug in ...

When Arduino debuted, most sensors and other interfacing devices ran on 5 volts. This tutorial shows how to hack your 5 volt Arduino board to run on 3.3 volts. It is a simple procedure involving ...
