Circuit ideas are everywhere! There are many places to find cool circuits.
The greatest sources for my inspiration are hacker/maker/electronics blogs, schematic webpages, hobby project pages, and open-source hardware companies.
How do you become better at electronics? By building lots of circuits.
On this page, you'll find circuit diagrams for a wide range of fun and interesting electronic circuits:
Transistor circuits. 555 Timer Circuits. LED Circuits. Amplifier circuits. And many more.
All circuits come with a component list and a connection diagram, schematic, or build instruction. So you can just start building right away.
If you have any questions about the circuits, just ask in the comment section of the circuit you're curious about.
I put together this Voltage Unit (VU) meter using LEDs on a breadboard the other day. It only has 4 LEDs, but can easily be expanded to more: It’s basically a simple display for showing a value. It’s originally for showing signal level in audio circuits, but there’s no reason you can’t use it to […]
Do you want to build a circuit that blinks a light? This inverter-based circuit is simple, and it’s small enough to fit on a breadboard. The circuit uses standard basic electronic components and you can build it even if you have never built anything before. Check out the full build instructions in the video below: […]
