Electric Scooter Lighting Firmware
This repository contains the source code of firmware for the additional board, which installed on my electric scooter and used for lighting management, namely:
- Turning lights
- Stop signal
- Daytime running lights (DRL; front and back)
When the button, connected on left turn btn is pressed - lamps (12V) connected to the left turn leds will be blinks (about 500ms lightning will be on). The same with the right turn btn and right turn leds. Stop signal button do the then thing, but on separate pin's.
Arduino board and LEDs use the same power 12V line.
Additional features
- When stop button is pressed - DRL back light lamps will blinks together with the stop signal;
- Five clicks on stop signal button enables DRL lights (DRL switch alternative; mode is stored in non-volatile memory);
- Triple-click on stop signal button enables stroboscope mode for the front DRL lights (mode is stored in non-volatile memory);
