I am waiting for 10 pcs (58mm) and 10 pcs (40mm) to be delivered. Watching to video from Aliexpress it is look like 4 for modes can be used to power on and off each device.
I want to use that COB lights to build some stars (5 long ones and 5 short ones).
What kind of circuit should I use to cycle power in order to change the modes?
Cheap and easy will be awesome
