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.
Created by Martin O'Hanlon, @martinohanlon, stuffaboutco.de.
Install and usage is really simple:
Get a Blue Dot app
Pair your Raspberry Pi
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.
You can press it, slide it, swipe it - one blue circle can do a lot.
The online documentation describes how to use Blue Dot and the Python library including Recipes and ideas.
Production - under active development. Be sure to raise an issue if you have a feature request or experience problems.
