Hi all...any electronics experts on here :stuck_out_tongue: I have built a small childs toy...it has 10 leds around the rim of the wheel (evenly spaced) I want it so that when pushed along, only the 4/5 LEDs facing forward light up. I have a magnet that can be used as a rotation/speed sensor...but…

Help please :) LED controlled by wheel rotation

How do you get power to the leds on the turning wheel rim? Battery inside the wheel?
