Posted on October 13, 2018February 8, 2019Jeep 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.
