I made an App that I can use to demo and test micro-controllers. I can send commands, test displays, use a controller to control robots or cars and receive data from the micro-controller.
The micro-controller has to be programmed with MicroBlocks.
This is version 2.
Blocks are more basic, so for beginning App Inventor users. A lot of when button click blocks. Total 626 blocks MicroBlocksRemoteControl2.aia (559.2 KB)
This works for instance with ESP32, Calliope Mini 3, micro:bit v2, M5Stack Core, Raspberry Pi Pico W, Citilab ED1, Adafruit CLUE, etc. All micro controllers supported by MicroBlocks that have BLE.
I made a simple Google Slides document with example code for App Inventor <-> MicroBlocks. For every screen in the app so you can see how to send or receive data. MicroBlocks Remote Control - Google Slides
Did my first test with the extension. This is all you need to get a connection with a MicroBlocks programmed micro controller and get info back. How easy can it be.
We had a great meeting with David Kim from the App Inventor team today. During the meeting the question came up if you could connect multiple micro-controllers using the MicroBlocks extension.
I started a little test and connected 6 micro-controllers using BLE at the same time that are sending values in real time to the app. I could probably connect more micro-controllers but this was a great proof of concept.
