The purpose of this code is to guide a biker using a ring of leds in the handlebars of the bike.
So, you can see arrow indications after pairing with a cellphone app. And a speedometer. And potentially a chronometer if you wish to code that too.
Code is written for a NodeMCU board, with a ESP32 with BLE chip. And the Adafruit LED Ring.
However, apart from the BLE library we use, the rest of the code should work on arduino too.
The framework we chose was Arduino, just because it has a great community. But apart from setup & loop main functions, we don´t actually make much use of it.
Preferred development environment is platformio, integrated to any IDE you would chose.
For Arduino IDE, open src/src.ino. And install FastLed library.
For other IDEs, like VSCode or CLion, you can run the main.cpp file. You'll have to install a couple of dependencies though, using platformio.
