1: found a dartboard. The one i settled on was a Winmau Soft Tip Dartboard, reasons being, is because it was the only one i could find that morning! at argos for £20. The code below may work for other dart boards. but it will deffo work with the WINMAU.
2 : Take the thing apart, annoyingly i dont have a picture of the inside! as i sold it and forgot! but inside basically is an arduino nano. which has all the wires from the ribbon cable that goes into the board, soldered onto a piece of stripboard with the arduino nano in it!, then an on and off switch and a midi out socket (search up “arduino midi out” !
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
