The bike jacket is composed of 3 features:
1- 2 tilt sensors on each arm to sense the right or left motioning of arms, flashing lights indicating right or left.
2- An accelerometer to sense the deceleration of the cyclist, flashing a red warning light on the back of the jacket.
3- An infrared sensor to the left side of the cyclist to sense if any vehicles or other cyclists are getting too close and sets off a small vibrating motor to warn the cyclist.
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.
