Brake light and turn signals for backpacks #CircuitPlaygroundExpress @hackadayio
Estudio Roble posts on hackaday.io a backpack project with electronic signaling. An accelerometer autodetects braking. The turn signals are commanded by a 315MHz radio module. 78 NeoPixels are used for lighting the indicators with an Adafruit Circuit Playground Express (CPX) controlling the project.
The remote of the radiolink is installed on the handlebar. By pressing buttons of one side or another, the turn signals are light up. They remains blinking as you keep the button pressed and 3 seconds after you released it.
An accelerometer autodetects the braking and change the default blue light by the red during half a second.
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.
