For now my app got no features exept
showing kmh, distance and wheel revolutions.
I would like to add:
-Battery indicator(battery status of the Speedometer)
-funktion to reset revolutions and distance-> in the app
-save revolutions and distance in eeprom of atmega 328
-max speed, average speed......usual speedometer features
Further i want to imrpove the Speedometer:
-using Bluetooth 4.0 BLE (already ordered some CC2541 modules)
-improving battery efficiency with another hall sensor (u18 already ordered)
-when all hardware is finally set i would like to make an layout and my own circuit board
Thanks to Till & Consti for the help!
