Electricians: start tinkering at low voltage

If you work with electrical systems and want to try electronics, start with low-voltage DC projects (a USB-powered board, 5 V or 3.3 V) on your bench, not panel work.

Suggested path

1. Blink an LED (ESP32 & MCUs section).
2. Read a sensor.
3. Drive a relay module that switches a low-voltage load.
4. Learn Modbus/RS-485 basics (posts below).

Even if you’re a licensed electrician, the projects here are bench projects at low voltage. Connecting a hobby project to mains or to a building’s electrical installation is outside what we cover, and in Quebec electrical installation work must be done by a licensed electrical contractor (RBQ/CMEQ). See the safety post.
