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.
Install and usage is really simple:
Download the Blue Dot app
Pair your Raspberry Pi to your Bluetooth device
Install the Python library
Write some code:
from bluedot import BlueDot bd = BlueDot() bd.wait_for_press() print("You pressed the blue dot!")
Press the Blue Dot
See the getting started guide to ‘get started’!
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. Perhaps create a BlueDot controlled Robot.
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.
