HeartBeat Sensor For Arduino Microcontrollers
This nifty little device is smaller than the size of a quarter. Place your finger over the heart shaped icon to read your heartbeat. Only three jumper wires are required to interface with Arduino based microcontrollers, some soldering is required. Alternatively you could solder some solid core wires and plug straight into any microcontroller that has a logic level of 5v. This device only consume 4mA of current.
Please make sure you insulate the back of the board from ESD by adding hot glue or taping the back.
