Control box for Saddle Vibrator

This is the control box and schematic for the Saddle Vibrator. https://www.thingiverse.com/thing:3554455

Code included for Arduino Uno (Master) and Arduino Nano (Controller) connected via a I2C bus for expansion and flexibility and the ability to add bluetooth or any other controller that can use the I2C bus. Otherwise, connect via USB, and create an program to control via the PC. The red momentary button sets vibration to 100% while you are holding the button, then resets to knob value, black button slowly ramps to 100% and holds until you press it again.

I will periodically update it with any updates and changes. If anyone has any suggestions on how to improve either the code or design, please PM me here.

Current version 1.0 (14.4.19)
