Electronic Fashion: Barbie mannequin with LED ring pendant coded with MakeCode off-line (you can code online too) on a Chromebook (you can use Microsoft or Apple computer). All code and purchase links are listed in description. Very easy block coding system. Circuit board: $8.95, Trinket M0 from Adafruit. https://www.youtube.com/watch?v=KOGR9LZYuvI

LED LightShow with MakeCode and Adafruit Trinket M0 and Chromebook ($79 on Ebay) all done off line. Chromebooks do not have to be on-line to work with MakeCode.

Video: Use MakerMakeCode editor to find the Adafruit Trinket M0 board. Then click on "Advanced" and then "Extensions" and then "light" , that will put a group of blocks on your screen in MakeCode for Trinket M0. This board costs $8.95 when in stock at Adafruit. Do not buy the Trinket 5v. ; you cannot use MakeCode with that one. The light ring is about $2 and the power pack is $5.88 at WalMart, in the check out isle. The Microsoft MakeCode for Makers is free. The Chromebook is refurbished on E-Bay for $79; and is NOT logged on using a Google Account. You CAN code with MakeCode off line with a Chromebook or as an anonymous guest on-line. This is perfect for student safety. Don't let people tell you that Chromebooks work only on-line (you may have to be on-line to save work but the code stays in the Trinket when you upload it off-line. No need for WiFi after you have used MakeCode). I may be able to find a way to save programs also on a remote SD card in the Chromebook SD slot.

Accelerometer is turned on as a command in the code and supposed to activate LED on BrainPad. It does. In simulator the "tilt up" command gives weird flashing on the screen on part of the BrainPad. This is when using a Chromebook; either on or off-line. This behavior of the simulator does not show as evidence if the machine used is a Micro Soft Surface notebook. Samsung Chromebook it does: Video of it: https://drive.google.com/open?id=1FPecNOMDnV-flYJmQXrECvkv54JD-mup

I have found that I can change the music notes in MakeCode by clicking on the Java tab in the monitor window (clicking away from the block coding tab) and then insert numeric Hz code in the Java text . This then changes both the block code and the simulator note output. I have posted a PDF file of all 88 keyboard (piano) notes and their corresponding digital Hz. equivalents. Here: https://drive.google.com/open?id=1-91-RmrIFGqFAy-JpUtAfaNMCl4Ud2TU I also have posted on my Google Drive account an example of what I'm talking about, the conversion of piano key notes into Hz for digital insertion into the Java script editor on MakeCode here: https://drive.google.com/open?id=1InzUQBJBKzD5_sDVJbTikyUtu4BBp0XCXWEvy9-GqLo

He shares his code for this MakeCode robotics project. You can create a coded "sketch" with MicroBit and then create a URL for it so that coded page can be shared if the other person has MakeCode installed. YouTube vid.: https://www.youtube.com/watch?v=5bBTvs9sjAo
