The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. This article contains a few examples of circuits that you might ...

An astable 555 multivibrator circuit, where the timing characteristics are determined by the interplay of an inductor, resistor, and diode.

The 555 timer outputs in astable mode, which means there is a continuous stream of pulses from pin 3 which go right into the speaker circuit. The rest of the circuit monitors the resistance of ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most widely used ICs due to its reliability and flexibility.

He uses a triggering circuit based on a 555 timer (PDF). [Rob] mentioned that if you shop around, you can get the relay, 555 timer, and other components for under $15.

Understanding DIL integrated circuits involves knowing their function and identifying pin one. The 555 timer IC produces astable and monostable outputs, requiring waveform interpretation and basic ...

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 ...

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 ...

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 ...
