BackLit - Turn signal device

# BackLit ## Turn signal/road communication device The project was developed over three months as part of the Hemda’s Makers course. The inspiration for the project came from a simple question: If every vehicle has a way to communicate with all other vehicles, then how come bikers don't have a way to do the same? When the question wasn’t answered by a Google search, we decided to answer it ourselves. And this is where BackLit comes in. BackLit is a real-time voice-controlled detachable turn signal/road communication device, meant primarily for cyclists and their safety while riding. ### To build one you will need: * Arduino NANO development board * HC-05 Bluetooth receiver/transmitter * Silicon wires * WS2812B Neopixel 5v LED's 60 LED - 1 meter strip * TP4056 micro USB charger * Step up Regulator * 18650 Li-Ion battery (You can recycle from old Laptop pack) * M3*12mm Allen screws - 8 units * On/Off 12mm circle switch * Android smartphone and download AMR-voice app to send voice commands ### Instructions: 1. Print the above files 2. Install the electronic hardware inside following the Electronics image 3. Check the Fritzing wiring scheme 4. Install the app to send voice commands ### Code: Download Arduino code from <https://mega.nz/#!rBlDWCRb> Please note that you will have to upload libraries Adafruit_NeoPixel.h. ### How to use? 1. Switch on BackLit 2. Launch the AMR voice app in your phone 3. You can choose LED colors - When you launch the App first say Red\Blue\Green\Rainbow then its ready for your direction prompts Left\Right ### You can: * Edit the code and add more colors/function/add other languages for right/left/colors Ride safe and please share
