Hey birdyberth. The TFT also gives a diagnosis after displaying your BPM.
If you have any questions. Ask me!
Birdyberth. Great project! Can you tell me your process to finding a heart beat. My circuit works, but when I add the electrodes the LED doesn't correspond and the oscilloscope can't read a beat.
It's the instrumentation amplifier. The instrumentation amplifier, is an amplifier that is particularly built for measurement. This will be measuring your heart rate. The other amplifier (operational amplifier) is to amplify the signal that the heart rate is giving off. The signal is so small that it needs to be larger in order for it to be read and later displayed on the LCD.
I am a student trying to learn electrical engineering. I am plugging my circuit and electrodes into the scope and I am only recieving static.Has anyone found a good place for the electrodes?
