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, ...

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 ...

The popular 555 timer can be used as a PWM/Class-D amplifier for musical instruments or other applications. It can use a wide supply range of 4.5-16V and produce 200mA of drive. The audio is fed to ...

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… ...

It’s an excellent way to learn about both PWM motor control and the use of 555 timers, all with a very low parts cost and readily available components. We’ve seen such setups before, used as ...

Last night, Signal announced that it’s going to allow you to set a disappearing message timer for all your new conversations by default. So you don’t have to set timers for individual messages ...

Simply adding a diode and potentiometer to a 555 timer operating in the asynchronous mode yields a pulsewidth modulator (PWM) with a duty factor adjustable from 1% to 99% (Fig. 1).
