Just about anything can be made with a 555 Timer, and every circuit is fun to build, which I show in my book “Essential 555 IC: Design, Configure, and Create Clever Circuits.” ...

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 is a pulse generator with adjustable duty cycle made with the 555 timer IC. The circuit is an astable multivibrator with a 50% pulse duty cycle. The difference from the standard design of a 555 ...
