Oh, I think I made those SMT pads inside the PCB layout window. I don't think that there is a schematic part for them. You can make pads, place them,...

Hi diontan524, That looks great! I will give your code mod a test run on the ATtiny85 that I have, and add notes to our master branch (and credit you)...

I have updated the Timer Interrupt Notes page here https://github.com/WorldFamousElectronics/PulseSensor_Amped_Arduino/tree/master/PulseSensorAmped_Arduino_1.5.0 There are Interrupt setup notes for ATtiny 85 running at 8MHz and also at 16MHz. They reference the Adafruit GEMMA...

Did you make any modification to the Pulse Sensor code? The Arduino sketch is defaulted to output for the Arduino Serial Plotter. Take a look at the read-me guide for...

I'm not sure what you mean by output to the serial monitor. What do you want to output to the serial monitor?

At the top of the main page on the sketch change the `outputType` variable to `outputType = PROCESSING_VISUALIZER` Then In the main loop, comment out the line `serialOutput()` by putting...

It looks like you need to update your Arduino. They are at v1.8.1 now. Can you share the code you're using? It does seem like you are missing some important...

I don't have the code handy, but it's not too hard to do. When a beat is found on one sensor, you can take the time and measure it to...

Oh, I see. You are placing the sensors on the same person in different places to derive PTT. Got it. Well, you should know which sensor is closer to the...

please contact me joel-at-pulsesensor-dot-com to discuss your project further and see if it's anything that I can help with.
