Arduino based Guitar Effects

There are lots of arduino projects that you can find online. But this one caught my eye and I am excited to make my own copy. Since I also love guitars and programming, this is perfect for my next project. It uses Arduino Due as the main processor. This project is published by and you can buy the kit for £39.95(not including the arduino due).

About Arduino

Arduino is an open-source prototyping platform based on easy-to-use hardware and software. Arduino boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board.

Arduino Due is one of their products that is based on Atmel SAM3X8E ARM Cortex-M3 CPU. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.



The circuit is simple and only consist of opamps, potentiometers and a power supply circuit to provide +5V and -5V for the opamps.

My Own Version:

I am not happy with the design because I want more features from it to be able to maximize the capability of the processor. I want to add some more functions like an LCD display and some more buttons. My goal is to have more presets and settings. I want it to be a multi-effects rather than a single effects so a LCD display will be a big improvement.
