I need to be able to plug and unplug the Arduino borad from the Pedal board while I am testing and adding features. For this purpose I’m using a 20 way plug and socket to go with the ribbon cable already installed in the pedal board.

I’ve soldered the socket to a piece of strip board then soldered in the cable being careful to match the correct wire with the appropriate pin.

On other other end of the cable I have soldered a piece of single core wire to each strand and protected it with heat shrink tubing. I’ll then be able to plug these flying leads into the I2C chips on the breadboard.

Next step, trial run and perhaps a YouTube video  (I’d better set up an appropriately named account.)
