Arduino MEGA Guitar Pedal

pedalSHIELD MEGA is a programmable guitar pedal that works with the Arduino MEGA 2560 and MEGA ADK boards.

The project is Open Source & Open Hardware and aimed for hackers, musicians and programmers that want to learn about guitar effects and digital audio using standard C/C++ and the standard Arduino IDE. You can get inspired using the library of effects posted on the pedalSHIELD MEGA online forum.

We created some documents so you can do the project easily:

• A pdf manual to build pedalSHIELD MEGA circuit in 5 steps.

• A quick guide to start programming.

• Have a look to the "BEST pedalSHIELD MEGA Forum Topics"
