Jeep Computer

Different prototypes of a relay controller for Jeep accessories.

This first iteration uses a 2-line LCD display.
Testing the new 4-line LCD Display
The newest prototype with 4 light-up buttons attached to each relay. It’s working, but the Arduino does not have enough power to keep 4 relays charged at once. I need to amplify the signal from the Arduino I/O ports.
A Raspberry Pi prototype that uses Python tkinter for a touch-screen UI. I don’t have any pictures of the UI, but it’s basically a full-screen 2×2 grid, each panel in the grid is a different relay switch.
