MicroPython Txting Package for micro:bit

Jun 1, 2017

The Micro:bit Foundation was contacted a while back by Will, a 13-year-old student, who had created a txting package for the micro:bit in MicroPython. In his message he said: "I love using Python with my micro:bit and I created a text messaging program in MicroPython". We were of course thrilled. The person who recieved Will's message wrote to the rest of the team: "A 13-year-old has written a lovely little communicator using Python and two micro:bits - something to consider for the website for an article perhaps?" There was, of course, no argument, so, eventually, here is Will's Micro:bit Txting Program.

Általános:

Press pins 0 and 1 together to cycle through the characters, press button A to add characters to the message and press button B to send the completed message. The script requires only 2 micro:bits and both can send and receive via MicroPython's radio module. However, more than 2 micro:bits can be used, just flash the same program onto multiple micro:bits and all of them can both send and receive. The actual Python code

• Texting_nocomments.py
