Afternoon, I'm looking to use a PulseSensor as a countdown clock. Everytime your heartbeats the numbers go down. I've not got the sensor yet but i've hit a little roadblock when i start to think about the code. So the PulseSensor on the example sketch library needs to be plugged into the analog pin…
