We are listing a curated collection of 555 Timer Circuits and Projects published in our site before. We have a large collection of simple and advanced projects using…
Ramp Generator Circuit-using 555 Timer IC We know that if a capacitor is charged from a voltage source through a resistor, an exponential waveform is produced while charging…
A voltage-controlled oscillator (VCO) using the timer 555 is shown in figure. The circuit is sometimes called a voltage-to-frequency converter because the output frequency can be changed by…
Are you familiar with the basics and applications of the 555 timer IC? Are you looking for a book that provides all these basics? If so, CircuitsToday has…
In this article, we are explaining an astable multivibrator, often called a free-running multivibrator. An astable multivibrator can be designed using different types of components, say using transistors (and…
Block Diagram of 555 timer IC: Comparator 1 has a threshold input (pin 6) and a control input (pin 5). In most applications, the…
Block diagram for the 555 timer is given in figure. As shown in the block diagram, a 555 timer consists of two comparators (simply op-amps), an R-S…
The 555 timer combines a relaxation oscillator, two comparators, an R-S flip-flop, and a discharge capacitor. R-S Flip-Flop. A pair of cross-coupled transistors is shown in figure.…
The 555 Timer IC is available as an 8-pin metal can, an 8-pin mini DIP (dual-in-package) or a 14-pin DIP. This IC consists of 23 transistors, 2 diodes…
555 Timer IC-Block Diagram, Working, Pin Out Configuration, Data Sheet – A complete basic tutorial This article covers every basic aspect of 555 Timer IC. You may already…
