Afrotechmods

Afrotechmods is an electronics tutorial channel taught by a professional electronics engineer. It also has a companion website.

The videos explain one component or skill at a time, with practical examples on the bench. Early tutorials cover the basics: resistance, Ohm’s law, diodes, transistors, voltage regulators and how to use a multimeter. Later videos go further into things like capacitor types, test equipment and microcontroller projects. The style is calm and direct, with little padding. New uploads are now occasional, but the back catalogue remains very useful. Each tutorial is short enough to watch in one go and then try out straight away.

Some highlights include:

A quick start guide to Arduino that takes a complete beginner to a working program in a short time.

A tutorial on diodes that ends by building a power supply that turns mains AC into DC.

A clear explanation of how transistors and MOSFETs work as switches, with practical circuits.

Afrotechmods has over 810,000 subscribers.

Few channels explain the building blocks of electronics as clearly. Watching these videos alongside a cheap breadboard kit is a practical way into electronic engineering. The Arduino and power supply videos connect directly to embedded systems, product design and renewable energy work, where engineers design the circuits that control and convert power.
