I have several working sensor cables for Spikerbit from sensor pads to expansion board with Micro:bit. I want to apply sensor patches on both arms (3 patches on each) and input via a 5X hub to the 3.5mm input on Spiker:bit, translate these signals and then output several “radio” signals from the Micro:bit to various rover cars with their own Micro:bit. How can this be done with splitter cables or coding or some custom system ?
