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 ...

However, it can be argued that since the exponential voltage of a capacitor is qualitatively similar to inductor current, the latter can be made an alternative timing element for the 555. This was ...

The 555 timer is used as a free running oscillator. We know that this not be very stable when compared to even the worst of crystal oscillators, but that’s what makes it work so well as a random ...

Pulse width modulators are a fundamental building block. Among other things, they are used for remote sensing, DC motor control, and switch-mode power supply controllers. This circuit uses a rail ...
