Hardware

I've added LED light effects to my MIDI keyboard.

This is what I've used:

• Wemos D1 Mini
• Prototype Base for Wemos D1 Mini
• PC900V optocoupler
• 220R and 10K resistors
• 1x2 and 1x3 2.54mm pitch screw terminals
• Male 5 pin DIN connector
• WS2812B 5V LED strip (powered via Wemos D1 Mini USB)

Note: schematic has a 1N4007W diode, but I have not used it.
