Electronic configuration

Currently, I use an Arduino Nano, an HC-05 Bluetooth module, and an OLED screen.

Tips

There is no README but the pinout is in .ino script 👍

Arduino

• Bluetooth connection
• "Watchdog" / feedback when Bluetooth is disconnected
• OLED Screen (128*64)

Android App

• Get location
• Get speed
• Display raw value and km/h value in a gauge diagram
• Send "{speed} km/h" via Bluetooth to the Arduino
