This circuit enables the on/off times of a 555 timer to be independently varied over a wide range. This is not possible with a conventional 555 circuit with the RC network being charged from the ...

In the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows the ...

Save guides, add subjects and pick up where you left off with your BBC account. The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the ...

In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use ...

The 555 timer IC has been reinvented—again. Signetics introduced the enormously popular chip back in 1971, and it quickly became a big hit. Myriad application circuits have used it throughout the ...

Hans Camenzind, the designer of the popular 555 timer IC died this week in Silicon Valley. He was 78. My condolences to his family and friends. Hans came to the U.S. from Switzerland in 1960. He ...

This stunning piece of art is [Emily Velasco’s] take on the Atari Punk Console. It’s a freeform circuit that synthesizes sound using 555 timers. The circuit has been around for a long time, but her ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...
