Just a preview of the dartboard project I’ve been working on in my spare time.
I finally got to the stage of the project where I was able to glue the separate pieces together and demonstrate a working example. Now to clean everything up and continue adding games!
Hardware/software breakdown: I’m using a store bought led-lit dartboard, which I have unsoldered from the factory pcb and am using one arduino to drive the led matrix, one arduino to drive the input matrix, a nodejs server running on a raspberry pi to handle game logic, and a react web app front end for the interface, which I have loaded on a fire tablet currently
This is the exact board I used: https://smile.amazon.com/dp/B077PBKL22/
Looks like it’s out of stock on Amazon now but hopefully could find elsewhere with “Viper 42-0003”
I found this one that is ~40% cheaper and in stock. Not identical on the outside but likely an exact match internally, so I would imagine all of the code/circuitry would work plug and play with this board as well: https://smile.amazon.com/dp/B08Y8QKJMD/
