Hello all !
I’ve purchased a bluetooth connected Ukulele that has a LED board under the fret, the Populele. Basically, the LEDs show where to put the fingers.
(demo : https://youtu.be/lA8_jI0H2dE)
I’ve noticed the the plugins to the LED board are standard and i can easily remove the micro controller to replace with one of my own, and make my own light show.
What I need to know is : is there anyway to benchmark it ? Like an arduino program then I hook to it, run and figure out which pin is what ?
By the way, the female JST connector connects to the board on the left side on the first pic, the male JST connector.
I added pictures of the female JST connector of the board and pictures of the original controller.
