Thanks Ivan Bosnic for the WifiBit from Croatia and help with the code to sense button press and temperature using Microbit and sending simple data to ThingSpeak for charting. I would love to find someone who understands more about the visualization possibilities offered by ThingSpeak service. This board costs only $17-18 US; so may be a good start point for tutors and parents to teach IoT data analytics --haven’t we had just about enough charts and graphs in this pandemic? ! ?
