Blinking Bicycle Light #WearableWednesday

Sure you could just buy lights for your bicycle, but isn’t life that much more enjoyable when you make your own? We certainly think so. There are few feelings that compare to replying to a compliment with a simple, “Thanks, I made it!” Here at Adafruit we’ve dabbled in some bicycle based projects:

Instructables user goldscrew made this blinking bicycle light:

Sometimes, when you ride a bike in the dark night. It will be very dangerous if you do not have warning devices for other vehicles such as: Reflective clothing, flashing/Blinking lights…

So, today I will show you how to make your own flashing/Blinking with IC NE555. You can attach this device to your helmet or wear it on your arm while cycling at night.

You are free to be creative and make any shape for these LED lights, like heart, star, circle….


Flora breadboard is Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!







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.
