In clearer terms, we’re going to create a pulse-width-modulation (PWM) signal using a 555 timer. This PWM signal can be used to apply a time indicating that something is activated, known as a ...

If you’re not familiar with the 555 timer, suffice it to say that this versatile integrated circuit is probably the most successful ever designed, and has been used in countless designs, many… ...

555 timer drives multiple LEDs from one NiMH cell 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 ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop… ...

A PWM circuit works by making a square wave with a variable on-to-off ratio; the average ‘on’ time may be varied from zero to 100%. In this manner, a variable amount of power is transferred to the ...
