Looking at my distributed BBC micro:bit clock I got to thinking, could I make a display screen using a number of micro:bits, using the radio functionality to update the screens ?To see if the basic timing would work I created some very rudimentary code on 4 micro:bits. Initially I tried to use the ‘display.scroll’ function. After much fiddling I did get this to work after a fashion, but in truth it looked rubbish. On the point of giving up I thought I would see what it would look like using the ‘display.show’ function. This produced a much more readable result so I decided to go on and develop some ‘proper code’. I had previously looked at with David Whale’s python ‘microbit’ module and this seemed a great way to get the text strings ‘into’ the micro:bit. which solved the problem of how to front end the display. The remaining s/w built used in my distributed micro:bit clock.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
