Automated water softener using an arduino, a relay, and code
The control unit broke so I made an alternative that responds with a couple of buttons to control a relay.
The difficult part is making it automated. The water softener has 5 different modes that require a specific time for each one to complete before moving on. The relay controls the motor which turns a gear that selected the different modes of the water softener.
Take and modify as you wish, this is my working implementation of the software.
