Friend asked me to write an android app. It will be control small car via Bluetooth.
How it works
It's simple - when I touch the screen, bits are sent into HC05 Bluetooth Adapter, which is connected with uC who can move the car via Voltage inputs.
Challenges I ran into
Deal with Bluetooth API, creating an app for old Android API 10 (My friend does not have new phone)
Accomplishments that I'm proud of
Nice and Simple GUI, graphical icons for horn and car's lights
What I learned
how to send everything I want via Bluetooth, handling multitouch gestures on old android api
What's next for Car Controller
controlling via Bluetooth using phone-sensors, maybe some drone?
