In short: I built a working ECG recorder out of an AD8232 module, an Arduino, three electrodes and a breadboard. Here are the parts, the wiring, where the electrodes go, and how to get the trace on a screen.
The heart has a vital role in our life, so being aware of its activity matters. This project was about getting the AD8232 up and running to record an electrocardiograph.
What you need
Putting it together
Read the AD8232 datasheet first. Once you know what each pin is for, the module is easy to use well. This is the build after wiring everything up.
Placing the electrodes
Seeing the signal
I wired up an LED and a speaker that fire on each heartbeat, which makes it obvious when the rig is working before you plot anything.
For the trace itself, the Arduino IDE's serial plotter is enough to start. MATLAB, Processing and PLX-DAQ all work too.
