Hi - first post to the forum, but I wanted to share a project I just finished that uses an MSP430G2553 with a DRV8833 H-Bridge, DC solenoid, float switch that is powered from a 9v battery. The goal of the project was to sense when the water level in the livestock tank need to be replenished and activate an irrigation valve and of course turn it off when the level is right.
Was a fun project where I made my first pcb, built a reflow oven with PID control, and made the whole thing waterproof. Links to the design files and software are available on our blog posting, but I don't have enoug
