In this tutorial, you’ll learn how to build a 555 PWM Circuit. You’ll modify the standard astable circuit with a couple of diodes. And you’ll see how you can use this to control the speed of a motor.
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.
