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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
