More lessons, three new labs, and your place saved
Give the basics a proper lightbulb moment
Expanded Learn chapters connect everyday analogies to circuit behaviour, measurement, signals and power. Move a control, make a prediction and see the idea respond. Sources are included for when a quick explanation turns into a rabbit hole.
Your place is saved
Continue learning brings you back to your last lesson, with the lessons you mark complete saved in this browser. No account needed. Take a break, make a coffee, then return without the familiar “where was I?” expedition.
Three more ways to play with the why
Logic Gate Lab, LED Bench and Transistor Switch Lab join the Playground. Flip inputs, change values and watch the result. Difficulty labels help you choose your next challenge, while theory detours explain why your circuit just did that.
