Electronics is the study of how electricity is controlled by small parts to make things work: a light that turns on, a phone that charges, a radio that plays. This section explains it from the very beginning. You do not need any math, tools, or earlier knowledge to start.
The articles are meant to be read in this order, because each one builds on the ones before it. Titles marked "coming soon" are still being written.
When an article is ready, it appears in the menu on the left under Learn, and each article has Previous and Next links at the bottom so you can move through them in order.
Small programmable computer chips, and how to start programming them. These pages are under Microcontrollers in the menu on the left.
