This wearable LED heart simulator pendant was inspired by my work as a cardiovascular surgical nurse as well as my love of electronics. It simulates the electrical activity of 17 different rhythms and when paired with the heart backplane, it becomes an audio and pulse simulator as well.
It is not so much a kit as it is highly over-engineered LEDs, but I hope you enjoy them anyway! The program will be loaded onto the eeprom for you, but you are more than welcome to use a propplug, provided by Parallax, Inc., to reprogram the Propeller chip with whatever program you would like!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
