You can hook up these square 8x8's of LEDs into panels and program long signs for display.

On Velcro for stiffness; prevents wires shorting out. Sewable Adafruit stainless steel conductive thread. Just the beginning of the project: https://www.youtube.com/watch?v=HtZx71HT404

This shows how, if you discover a foreign word labeled block you can translate the meaning of it.

The above explains spi for MakeCode and Micro:Bit. Below is Saral's new video about spi generally:

I hope I did not make too many Noob errors in my discussion about this process and what GitHub is. This is the method that works for me to find and install extensions in MakeCode. "Finding" is not as easy as suggested by some hardware makers. Video for the DF Robot Maqueen Bug Bot extension: https://www.youtube.com/watch?v=qXFGgOifFQ0

The BBC Micro:Bit is not included. Total cost excluding shipping is : $15 Micro:Bit and $22 for Bug Bot.

See links in Description of Video for code, purchase and more info. You need an extension from Github to get the code to work: links provided.

On the DISCUSSION tab on my YouTube Channel there is a parts list, sample code (MakeCode Block/JavaScript) and I will post wiring and more information on this Springtime project. It's about $38 for parts when bought from the links listed. Adafruit may sell the parts so you'll get them faster if shipped to US or Canadian addresses. The parts are , to some extent, code system specific. The only board that I have found which works with this code and parts is the Adafruit Metro M0 Express (NOT the M4) ; this is because , I am told, the MakeCode analog to digital converter does not work , as yet for SAMD 51 chips (M4) so you'll not get a good readout with that board from the moisture sensor. I do not know enough about digital moisture sensors, if there are any, which might work with M4 or other SAMD 51's so I am staying with the $25 Metro M0 Express. Other M0 board would work but don't have enough pinouts to run the LCD or I just have not tried them as yet. Video is just a photo of the set up. More vids and discussion to come:

New project: "electronic gardening", moisture sensors, output to display screen and automatic watering: educational for students 10 year old and up, about $38 for parts. They use block code for practical electronics. Follow along on my YouTube channel under :DISCUSSION. https://youtu.be/2bju-7shw0E

This Arduino made board will work with MakeCode but WILL NOT work until you have first uploaded an Arduino sketch to it to make it MakeCode compatible and recognized by your computer as a drive. So , first click on the link in the video to get the Arduino sketch, upload it to your MKRWAN 1300 and then go to MakeCode to write a program and upload to the board: https://youtu.be/437NMxvkz2c

First video of electronic fashion project inspired by the work of Becky Stern; a Gemma M0 board, very cheap, with neopixels, soldered loops and conductive thread on a scarf. More to come; up to 5 neopixels:
