I am new to this topic, previously I post under Codemaster.

Recently I start playing with microcontroller board, like Arduino and Microbit.
Raspberry Pi Pico is very new microcontroller board, but only costs USD 4, way cheaper than Arduino Uno (USD 23).
Does anyone here play and learn with Internet of Things?

Does anyone here a regular customer of Cytron? (They also have a technical forum, but inactive like this topic)
