It can be used in power supplies and converters etc.IT can be used in tone generation or logic clocks.It can be used in LED or flash lamps to turn the lamp on for a specified time.It can be used in one-shot or delay timers to produce a time delay.Related Post: Simple Touch Sensitive Switch Circuit using 555 Timerĥ55 Timer IC is a useful precision timing device produces single pulses or as an oscillator producing a string of stabilized waveform of any particular duty cycles.The output from flip flop can be used to control a high current output switching stage to drive the connected load producing High or Low level at the output pin. The output of both the comparators is connected to the input of flip-flop to produce either a “High” or “Low” logic output based on the states of Input. The voltage difference is determined by the externally connected RC network. The two comparators produce an output voltage that depends upon the voltage difference at their input. This produces a voltage divider network at Pin 8 and Pin 1. There are three 5K ohm resistors connected together internally. Let’s see the internal circuitry of the 555 Timer IC to get a better idea of its working principle: 555 Timer IC can be mainly configured in three different states namely A-Stable multi-vibrator, Mono-Stable multi-vibrator, and Bi-Stable multi-vibrator.

Related Post: How to Make a Simple LED Flashing Circuit using 555 Timer ICĥ55 Timer IC is used in timer, pulse generation, and oscillator applications.Before that let’s take a brief idea of the 555 Timer IC. We will be discussing all the four-timer circuits (1Min, 5Min, 10 Min and 15 Min timer) one by one throughout this article. The main role in this circuit is played by the 555 Timer IC. We can use the different timer circuits of a different time delay to operate an alarm, a device, motors, etc. To create the timer circuit for the desired time interval, simply change the value of the resistor R 1 or Capacitor C 1. We can use this oscillating behavior of 555 Timer IC to create the timer circuit of different time delays. Which means that the output pin3 of 555 Timer IC is in “OFF” condition for some time and again comes in “ON” condition after a pre-set time interval. Also, 555 Timer is used to generate an oscillating pulse.
Here, with the help of the 555 timer IC, we are eliminating the need of manually switching ON or OFF the device. In this project, we are using 555 Timer IC to create various timer circuit like 1 min timer circuit, 5 min timer circuit, 10 min timer circuit, and 15 min timer circuit. In other words, if you are looking for an automated device to work for a certain time period and switch off after the desired time then this Timer Circuit is the best choice to opt. Timer circuits ease your day to day tasks in many ways by initiating or doing it in a definite time interval.
In the era of technologies, everyone is taking the help of machines to simplify their life.
