Integrated Circuits and Digital Logic
For Smaller, Better Performing Projects
Integrated circuits pack tiny resistors, capacitors, and transistors onto a small silicon chip, making circuits like comparators, counters, flip-flops, display drivers, and timers more compact and easier to use. Browse the tutorials below to see how these circuits can enhance your projects!
555 Timer Basics – Astable Mode
Learn about the 555 timer and how it works in astable mode. It’s a simple source of oscillating current that can power blinking LEDs, generate tones, and lots of other useful applications.
555 Timer Basics – Monostable Mode
Discover the basics of the 555 timer and how to set it up to operate in monostable mode, along with a sample circuit you can build yourself.
555 Timer Basics – Bistable Mode
Learn the basics of the 555 timer and how it works in bistable mode. In bistable mode, an LED is switched on and stays on until the reset button is pressed.
