The examples of using this sensor (on the pulsesensor.com website) start with a blinking single color LED and rapidly go into examples interacting with Processing and other computers.
This leaves room for a very interesting application: using the pulse sensor values to vary addressable LEDs such as Adafruit’s NeoPixels. From a single pixel to circles (or a heart shaped design), to a costume full of pixels, people will know when your heart is racing!
This project is inspired by and designed with Laura Barela.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
