My friend and former college professor Yury Gitman posted up this time lapse video of him and his business partner Joel Murphy making and packing up 800 pulse sensor kits. Nice!
The Pulse Sensor Kit is a kit. It does contain an assembled PCB Pulse Sensor, but it also has a collection of other supplies that you need to get the most out of the Pulse Sensor: a Velcro strap (to wrap the sensor around your finger with), an ear clip, and vinyl dots (to make the sensor more comfortable and reliable when contacting direct skin). It doesn’t sound like a lot, but using these helps you get good long-term readings. Unless you are a seamstress or jewelry designer, these parts are not exactly effortless to source. We tested a lot of Velcro straps and ear clips before selecting the ones that finally made it in our kit.
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.
