This is a list of hardware to be used in the project
Sheet metal box, two rows with buttons. One LED above each button.
14 pcs SPST Momentary Push Button
Neopixel – 5 mm RGB Diffused LED -WS2811
To use 14 buttons I need to enhance the number of inputs in the UNO. I will use a multiplexer CD74HC4067 with 16 inputs/outputs. I’ve bought it mounted on a breakout board. www.electrokit.com
Panel mounted adapter cable USB-B till USB-B.
More to come.
