Blue Dot allows you to control your Raspberry Pi projects wirelessly – its a bluetooth remote and zero boiler plate (super simple to use 🙂 Python library….
…The Blue Dot is a joystick as well as button, you can tell if the dot was pressed in the middle, on the top, bottom, left or right.
Why be restricted by such vague positions like top and bottom though, you can get the exact x, y position or even the angle and distance from centre where the dot was pressed.
Its not all about when the button was pressed either – pressed, released or moved they all work.
One blue circle can do a lot.
