Metronome with 4 leds?
There are projects like that in instructables and youtube but they're all 2 leds and a speaker.
They go 1-2-1-2-1-2-1-2-1-2
I want it to go 1-2-3-4-1-2-3-4-1-2-3-4
it would be pretty cool with different color leds.
What would it require, probably similar materials to the instructables, but less cause there is no speaker.
How would the circuit look like?
