    Time as come to put the Line 6 pedal board back together. I decided to call this particular board the Line 6/PU-1. I hacked it… then it is mine! The behringer FCB1010 will probably be the PU-2… The PU-1 will serve as a test bed for new ideas and prototypes. Each subsystem has already been…

    I decided to take a closer look at the main board from the Line 6. Since I might be tempted to put a simple display on the pedal board, in addition to a 16 character x 2 lines display, I decided to remove the digits from the (old) main printed circuit board (PCB). But taking…

    The expression pedal board contains two analog circuits for the two pedals, a simple switch and a LED. The connector has one pin for each, plus a ground and Vcc pin. The pedals use an infrared LED and photo-transistor that is slightly amplified by a transistor. They produce a weak analog value. I have not…

    After the midi episode, it was time to write the code to get the pedal press signals and control the LEDs for feedback. The pedal switches use what is called a resistor ladder: each switch is linked to a particular resistor, in series, and in theory, reading the resistor value at the end of the…

    The Line 6 Pedal Board will now receive an Arduino to replace its main board. The goal is to attach this Arduino to a computer using midi on a USB connector. For testing purposes, I will use an Arduino Duemilanove that I have on hand. I will use an Arduino sketch to test the midi-to-USB…
