I picked up a couple of micro:bits out of curiosity and was impressed by the build quality. The after-market eco-system was impressive too, and I wrote a couple of projects to see what I could do with them. My favourite has to be the Wireless MQTT client (https://petergarner.net/notes.php?thisnote=20220502-BBC+micro%3Abit+as+a+Wireless+MQTT+Client.html https://petergarner.net/notes.php?thisnote=20220502-BBC+micr...) which used a bolt-on IOT module card. Prior to that I'd installed a micro:bit in a small leakproof sandwich box bolted to a drainpipe which transmitted light level and temperature value to my computer inside the house (https://petergarner.net/notes.php?thisnote=20200125-Experiments+with+IoT+LoraWAN.html https://petergarner.net/notes.php?thisnote=20200125-Experime...). Hats off to whoever designed the device as it withstood sub-zero and summer temperatures without faltering. Great times!
