Polite Passing and Safer Bicycling – the talking bike helmet with turn signals ** Version 3 ** Nicla ME gyro over BLE for trigger sensing

Make the World a Better Place : Polite Passing and Safer Bicycling – the courteous talking bike helmet with turn signals 

reference the Version 1 for some background and a video

/challenges-projects/project14/betterworld/b/blog/posts/polite-passing-and-safer-bicycling-the-talking-bike-helmet-with-turn-signals-version-1

This Version 3 helmet is to use the Nicla ME mounted on the bike helmet to transmit gyro signals to the Arduino Nano Sense 33 on the handlebars 

via Bluetooth BLE for triggering the turn signals or by pushbuttons on the handlebars. The audio and speaker would be moved to the handlebars. 

The turn signal LEDs would still be on the helmet. 

Here are the schematics

Here is a photo of my test rig with my project helper Pinocchio.

Pinocchio's talent is software.

Its a great team complement, Im more of a concept dreamer and a hardware person.

Here is Pinochhio coaching me on BLE coding. Funny, his nose didnt seem that big before...........

Here are reference documents to help guide in the design of BLE code using Nicla and Arduino.

The Better World with Arduino ends tomorrow May 25th. 

I'm submitting the project without the application code being operational.  The BLE code can be written in a multiple number of ways, the first 1000 ways I tried dont work. It will happen tho.  

Even without functional code, the World is better with Arduino.
