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 www.electrosmash.com/ 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.

Schematic
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.
