I show and explain all the steps from wiring to tuning. Finally, the men's body groomer plays its interpretation of the song When The Saints Go Marching In. To turn the device into an instrument, we need to control the motor. And that takes some electrical engineering. I open the casing to expose the motor. I connect some wires to the motor by soldering and then close the casing. Now we can change the speed of the motor by changing the voltage of the current. The higher the voltage, the higher the RPM, and the sound. To play a melody, we need to automate the voltage change. I do that with the help of PWM (pulse width modulation). I implement the PWM using an H-bridge and an Arduino microcontroller. I tune the device using a guitar tuning app. I find the correct PWM values for each note. After that, I tell the values to a program on my computer. The program can read a sheet music file and translate that into a form that a microcontroller understands. And finally, we can play the song on the device. This is my first making-of / behind-the-scenes type of video (in a long time) and I made it by popular request.
