PREVIEW – ESP 32 Wristband – LilyGo-T-Wristband
Neatly packaged in a silicone wristband, this is the smallest version of the ESP32 that I know of. The ESP itself does not have its own programmer. However, there is a kit that contains the wristband and a programmer. Once initialised, the wristband can be updated via OTA.

CodeShorty: Wire Scanning (Uno)
The I2C, also known as the 2-Wire bus, works with two wires and theoretically at speeds of up to 5 Mbit/s. For hobby use with open-air wiring, it's likely to be less. The Uno has the Wire connection on analogue outputs 4 and 5. To test, I connected a GY-68 barometer which is on port 0x77 of the...
