This is my Light-Bag bike project with Arduino.
Making the RGB leds blink to the left/right, while controlling them with a RC attached to the front handle. Arduino Nano with 2 RGB led strips, attached to bag pack and operated by 4 channel RF control. This project made for rear signaling when riding a bike.
The remote control connected to the front handle with Velcro. Software
