ardEEG shield uses Arduino as a brain-computer interface

The result of several years of work on the development of a brain-computer interface (BCI), it looks to measure EEG, EMG and EKG readings with an Arduino.

Basically, the creator – “Ildaron”, a researcher at Heriot-Watt University – wanted to provide an easy way to get started with biosignals using an Arduino shield.

Thanks to the Arduino team for highlighting this one:

He writes:

“Connect the shield to Arduino Uno R4 WiFi and after that connect the device to a battery (power supply) and connect electrodes. Full galvanic isolation from mains is required. Electrodes are positioned according to the International 10-20 system.”

It’s a complicated project. Not least because, for the code, Arduino script apparently does not allow reading data from the ADS1299 with a frequency of 250 Hz. It’s necessary to use .c or .cpp scripts for reading data in real-time, he highlights, and Python for signal processing and visualisation…

You can read more about the ardEEG on GitHub, and see the output of his shield (from opening and closing his eyes) in the video below.
