    Because of the previous post, I decided to  test a bit more. To see if I could physically move the board to reduce interference. So I connected the Arduino with the attached RFM12B radio module. The one using the Sparkfun MIDI breakout board. As I was clearing the desk, I placed the Arduino on a…

    This is a screenshot from the serial monitor of a Jeenode (Arduino compatible) connected to my computer. It runs a program that will listen to incoming radio messages through its RFM12B radio transceiver. In this window, you can clearly see too lines that start with “OK”. These are real messages coming from my EM-1 Energy Monitor.…

    If you were patient enough and read through the two previous posts on this subject, you might be wondering how this applies to the PU-2 pedal board in practice. Even if you were not patient enough, here’s how the data structure will be used: The data structure was developed to provide a very simple programming…

    Seven whole days! That’s how long I had to work to finally get my rotary encoder to work with the Arduino! The idea is to be able to quickly select a preset on a guitar pedal board using a rotary encoder instead of a couple of push buttons. The rotary encoder I’m using uses pretty…
