Scratch GPIO + PI – Liter

A while back I posted about the pi liter,  I now.  I spent part of todays pi jam working on this with one of the young people who attended.

Once we had found the info pins, which we got from the product specification / information sheet we could figure out how to make all the LEDS light up in sequence.

The program was then improved further by adding some interaction,  press up / down arrows to change speed,  user input for speed. and a few other things q / p to stop / start.

Works well.   Code can be found at https://github.com/zleap/RaspberryPI under pi-liter/scratch.  You can download in the usual way from github.
