LM324
Low-Pass filter amp for slow pulse, EKG, action potentials etc
This op-amp circuit is mainly a Low-pass filter and a DC block and can be used to amplify pulse with an LED and LDR or even measuring the heartbeat with electrodes. It can be attached to the arduino or into the line-in of your computer,
