electronics becomes bioscience
Start with a circuit.Arrive at a signal.
ardEEG brings eight channels of EEG, EMG, and ECG acquisition into the Arduino UNO R4 WiFi ecosystem—an open path from electronics learning to biosignal experiments.

01 / Instrument position
The first biosignal experiment can begin with a familiar board.
ardEEG keeps the learning curve continuous: Arduino handles the code and wireless route while the shield adds the electrode interface and configurable acquisition layer.
02 / Signal route
Upload. Connect. Observe.
The learning experience follows a concrete sequence, from Arduino code to electrode contact and a visible signal.
