1. Getting Started with ActivityPub
ActivityPub is a specification for a decentralized social network. Decentralized here means that anyone can run a node that is a full member of the network. Anyone on any server can follow, like, and communicate with any member on any other server.
The W3C recommended the official ActivityPub spec in 1998, but it's gotten more attention after Elon Musk bought Twitter. When I started looking into the spec, I couldn't find anything that explained how to implement it, so I thought I'd write up som…

Presentation
The music box is an MP3 player with 6 playlists, volume buttons, previous, stop and next buttons.
Here are the components:
ELEGOO nano (4€)
DFPlayer Mini (3.5€)

1. Why I write posts on Dev.to, and you should too
I have written nearly thirty posts on Dev.to and supplied countless (constructive) comments on posts of others. On the whole, I have found the experience rewarding and the community appreciative and supportive, even when they disagree with me. Here are the three main reasons why I will continue to write and I suggest you try it yourself, if you have not yet done so. If you already write posts, perhaps you might want say why you do in the comments below.

2. MicroPython officially becomes part of the Arduino ecosystem
Last month MicroPython officially became part of the Arduino ecosystem. The inclusion of MicroPython as a member of the Arduino family is an exciting development for those interested in using Python to develop for any board with a serial REPL interface, like the ESP32. The ESP32 is a low-cost, low-power system-on-chip (SoC) microcontroller with built-in WiFi and Bluetooth capabilities, making it a popular choice for a wide range of projects, including IoT devices, home automation, and wearable e…

From Wi-Fi to Li-Fi, sending data via light using Arduino and JavaScript
Different parts of the electromagnetic spectrum can be used to transmit information. Using visible light, data can be encoded and transmitted using a technology called Li-Fi which aims at using your existing lights for wireless communication.
