Controlling a Raspberry Pi robot using a BBC micro:bit

Showing how the accelerometer on the micro:bit can be used to send information to a Raspberry Pi computer to control a robot. The communication between the micro:bit and the host computer is done using pyserial with MicroPython on the micro:bit and python on the Raspberry Pi and on the robot.

hello steve, that looks awesome m8! any chance of a diy video tutorial on building the robot, writing the code and conecting the bit to the pi?

Stewart, my name is Michael. I could use your help building something that I know nothing about. I am seeking help to build a small circuit board that runs on a small battery and sounds a "beeping" sound, (kinda like a smoke detector with a low battery) whenever a contact is broke. It needs to continue beeping until its shut off by a switch. So imagine a bedroom door with a contact on the door and on the ceiling. When the door opens, the contact is broke and the beeping begins and doesn't shut off when the door is closed back. It won't shut off until you switch it off with an on/off switch. If you understand what I am meaning, would this be difficult for you to explain to me how to do?

Hi, my name is Bence.
I would have two questions.
Firstly, how can I send data from the micro:bit to a computer ? Also what programming language are you using ?
Secondly, could you send data like this wirelessly ? I mean without using USB cable with the micro:bit.
I woul appreciate if you could answer thr above questions. :)
