Shower Controller - Manage Shower Length | [0016] 🚿
After dealing with excessively long showers for too long, I set up a system to manage the amount of time our kids could effectively use the shower.
Schematic can be found here (pdf)
Code can be found on GitHub.
Parts (not a complete list, mostly the electronics side):
Brass Liquid Solenoid Valve (adafruit.com)
Rugged Metal Pushbutton with LED Ring (adafruit.com)
Arduino Pro 328 – 5V/16MHz (sparkfun.com)
MOSFET (digikey.com)
Schottky diode (digikey.com)
This is version 1 f the valve setup. This version was flawed for a couple of different reasons (explained in video).
This is version 2 of the valve setup (shown installed).
The electronics. The yellow wire on the Arduino is a bodge and unrelated to the functioning of the shower controller.
