Next we cut out a little circle of conductive fabric and split it in two and sewed them onto the left shoulder blade. We took conductive thread, sewed it into the VBATT hole, and connected it to one of the conductive fabric circle halves. We then sewed a new piece of conductive thread from the unused half circle, and connected it through all of the positive ends of the LED lights.
By interrupting the circuit using the conductive fabric half circles, when someone wearing conductive thread on their right wrist, the circuit will complete when they put their arm around the person wearing the sweater.
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.
