I am trying to interface the TinyDuino with the pulse sensor (http://pulsesensor.com). Can someone provide a bried hookup guide.

Thanks,
Subhradeep Dutta

Hi Subhradeep- it should be very similar to using it with an Arduino Uno like shown in their guide at https://github.com/WorldFamousElectronics/PulseSensor_Amped_Arduino , but you will need to solder the wires to one of our prototyping breakout boards or use our terminal block proto board. Connect the power wires to GND and VCC, and the signal to A0 as indicated.

Thanks,
Ben
