Simple timer circuit using Ic 555

In astable mode, the output from the 555 timer is a continuous pulse waveform of a specific frequency that depends on the values of the two resistors (R A and R B) and capacitor (C) used in the circuit (fig 1) according to the equation below.Astable mode is closely related to monostable mode (discussed in step 2), you can see that the schematic is nearly the same.

Two Step Sequential Timer. The above circuit can be modified to produce a two step sequential delay generator. This circuit was requested by one of the avid readers of this blog, Mr.Marco. A simple delay OFF alarm circuit is shown in the following diagram. The circuit was requested by Dmats. The following circuit was requested by Fastshack3


Simple Delay Timer Circuits Explained

In this 555 Timer tutorial, you'll learn how to use the 555 timer to do fun things. One of the first things many do with it is to create a blinking light. But that's just one simple example of the many things you can do with this chip. You can also control motors, create an alarm, create a musical instrument, and much more.


Simple long duration timer

Here i am going to explain different ways of building adjustable timer circuits. However, these methods are cost ineffective.Three circuits are explained here are 1)Simple adjustable timer using 555 IC,2)A cyclic on/off timer using 555 IC,3)Adjustable timer using arduino. (40+ Simple 555 Timer Circuits & Projects)


On Off Timer Switch Circuit

So to build 1 minute (60 seconds) timer we need resistor of value 55k ohm and capacitor of 1000uF: 1.1*55k*1000uF. (1.1*55*1000*1000)/1000000 = 60.5 ~ 60 seconds. A variable resistor of 1M is used here and set on 55k ohm (measured by multimeter). We can easily calculate the resistor value for 5 minute, 10 minute and 15 minute timer circuit:

Simple Programmable Timer Circuit. Last Updated on January 2, 2024 by Swagatam 452 Comments. This programmable timer can be used for switching a load ON and OFF with two sets of time delays, which are programmable from 2 seconds to 24 hours independently. The delay timings are adjustable according to the users personal specs.


Simple Time Delay Circuit using 555 Timer

The 555 timer IC is a very cheap, popular and useful precision timing device which can act as either a simple timer to generate single pulses or long time delays, or as a relaxation oscillator producing a string of stabilised waveforms of varying duty cycles from 50 to 100%. The 555 timer chip is extremely robust and stable 8-pin device that.

1 Minute Porch Light Timer. This 8th circuit shows simple porch light timer circuit that can be activated for a minute only during night time. During day time the LDR resistance becomes low which keeps its junction with R5 high. Due to this, pressing S1 has no effect on pin 2 of the IC. However, when darkness falls, LDR resistance goes infinite.
