The details of the headers and their functions are described below.
JP3 headers are arranged in such a way that the whole module can be plugged into the left-side female headers of Arduino Uno or chipKIT Uno32 board, as shown below. Depending upon the position of the JP2 jumper, the output PPG signal can be fed to A0 or A1 analog channel of the Arduino board. If you want to use it with chipKIT Uno32 or any other 3.3V platform, make sure the JP1 jumper is placed on 3V3 position. The on-board potentiometer is useful to adjust the overall gain of the amplifier.
Easy Pulse Plugin is now also available for purchase in limited quantity on my Tindie Store.
Hi Raj, can you provide me with a schematic diagram for the circuit on the breadboard when connected to arduino UNO
