The 555 timer IC remains iconic and widely used. Let's explore its enduring appeal through simple, fully tested 555 projects. No programming required!

Whenever I use the 555 timer, it seems that the output polarity is invariably incorrect, and the way the 555 functions, it ... Since the VGS(OFF) parameter is sloppy (-1 to -5V), the device must be ...

Using a CMOS 555 timer, you can drive seven high-brightness LEDs from a single 1.25V cell. Analog switch converts 555 timer into pulse-width modulator Added CMOS switch enhances a PWM oscillator. Use ...

This one is simple for beginners, ... In a PWM circuit, the 555 timer will output a logic signal “high” and “low” depending on a ratio derived by the value of a few components connected.

From a simple frame that stays out of the way to being the central nervous system. ... But it’s cute, it’s a 555 timer circuit, and it’s shaped like a robot. That all makes it a win.

Each of the candle lighting circuits, however, use a 555 timer both for its intended purpose of providing a timed power-on reset pulse, and another 555 is used as a simple flip-flop. It’s a ...
