Using the ADC Pi or ADC Pi Plus with Arduino

Created 02/10/2015 | Using the ADC Pi or ADC Pi Plus with the Arduino range

The ADC Pi v2 can also be used with the Arduino range of development boards or any other processor which has an I2C interface.

The Arduino library for MCP3424 from ArduSat allows you to easily use the 8 different analogue inputs on the ADC Pi with your Arduino project and stack up to 4 ADC Pi v2 boards giving you up to 32 x 18 bit ADC inputs.

You can download the library and sample code from

The image below shows how you can connect your ADC Pi to your Arduino UNO using only 4 wires.
