“A 555 timer circuit with a 10k potentiometer and 9 LEDs for those times you just want to kick it up a notch.
Bridging out from my last post on the 555 timer LED Blinkie, I decided to make something a bit more exciting. I had an idea for a pocket strobe light/flashlight I wanted to build with an adjustable potentiometer. It’s a variation on my original 555 Timer Blinkie Circuit but with a potentiometer that allows you to adjust the frequency of the blink, giving you a strobe like effect. Ideally I’d like to make a version that responds to sound with a sensor but manual input works for now.
Our 555 timer circuit today utilizes the astable operating mode with a 10k potentiometer to adjust the speed of the flash. We will be doing both breadboard and PCB design in this tutorial.
Let’s Lay it Out on Our Breadboard
First things first, layout the components we need to use for the circuit.”
