Digital Tachometer Circuit Diagram. This DIY digital tachometer for bikes uses two reed switches to get the speed information of the bicycle The reed switches are installed near the rim of the wheel where permanent magnets pass by The permanent magnets are attached to the wheelspokes and activate the reed switches everytime they pass by it The speed is digitally displayed.
