In a shopping frenzy, I couldn't resist and ordered the new power pack from Arduino. The 33 IoT is in the form factor of the Nano but has Wi-Fi. It also has an integrated IMU with which acceleration and spatial orientation can be determined. More about this amazing board in the following sections. …

Hardcoded SSIDs and Wi-Fi passwords in Arduino code are not a good thing. Entering Wi-Fi credentials via the console is no longer up-to-date, especially if you don't have a console connection. It would be nice to have a general solution that allows IoT devices to be easily connected to your own Wi-Fi without having to already have something in the code...

The WeMos D1 R32 is an ESP32 housed in an Arduino Uno form factor. It looks like an Arduino, but its I/Os only operate at 3V instead of the usual 5V. This can lead to incompatibilities with expansion boards (shields). The price is under 5 Euros on fast shipping sites like AliExpress. The board features all the advantages of the ESP32 processor…
