- Arduino Self-Bondage Controller
The wiring is fairly simple (especially if you use the display module). Wiring diagram will be provided in the future. The prototype uses a USB cord from a USB battery for power. Four buttons (stop, hours, minutes, start) wired from ground to their respective input pin provide the input. A pull-up resistor to VCC (+5V power) is recommended especially if the buttons are wired away from the circuit board. LEDs are wired from ground to their output pins through a resistor (should be 510 ohm, the prototype is stupid bright with 330 ohms). The display just needs +/- power and 2 data pins. Wire the output through a MOSFET transistor. That is all.
The code is as follows:

This version uses the LEDs for the remaining time.
