In this post we learn how to build a simple yet accurate timer circuit using the IC and some ordinary passive components.

Main Advantage of using IC as the Timer IC I have already discussed this IC comprehensively in one of my previous articles, everything regarding its pin outs have been discussed there in detail. We studied that the IC is specifically suited for timer applications and also as an oscillator. Other than the IC you would require just a couple of resistors, one pot and a capacitor for making this timer. Referring the figure, the simplicity of the design becomes evident and therefore this circuit is perfectly suited for all electronic newcomers, who can easily build this project and enjoy its useful service.

As explained earlier in one my articles, the IC has an in built oscillator that needs just a few passive external components for making it tick. Depending upon the values of the external RC components, the oscillation periods can be varied right from a few fractions of a second to many hours.

RC components refer to the values of the external time determining components consisting of a resistor or a pot and a capacitor. Since here we want to use this unit as a timer we have selected the pinout which is last in the order as far the length of the time period is concerned, meaning we have selected pin 3 which generates the highest delay period.

The biggest advantage of making a timer using IC is that the involved timing capacitor can be kept as small as possible by increasing the complementary timing component value, which is the resistor. This helps to keep the circuit simple, smaller and very sleek, unlike other timer IC like which require high value electrolytic capacitors for generating even ordinary time delays. How the Circuit is Latched when Time is Elapsed In the figure you can see a diode being introduced from the output pin 3 to one of the oscillator pin This diode acts as a latching component, which latches the IC once the set time lapses and the output of the IC goes high.

If this diode is not inserted, the output would go freewheeling from logic high to logic low and keep repeating the time delays. The circuit may be powered from a small 9 volt battery which will last almost for ever. A buzzer is fitted at the output for the required indications of the timer output after the time delay has elapsed. How to Reset the Timer The IC may be reset simply by pressing the reset button or alternatively the circuit gets automatically reset when switched off and powered again.

Rt will in Ohms and Rt in Farads PCB Design Adding a Relay You can further upgrade the above design by adding a relay control to the output in order to facilitate an external mains AC load switching, as shown in the following image: Remember the delay interval at pin3 can be increased by increasing the C1 value along with the P1 pot value.

Hoover, make sure that the C1 is always a non-polar, hence to increase its value you can connect many number non polar capacitors in parallel.

For example you can connect non-polar 1uF capacitor as many numbers as you want for getting a desired long delay. The schematic for the circuit discussed in the video can be visualized in the following diagrams: The following image shows how to latch IC output by adding a diode across the selected output pin and pin 11 As we already know that the timing output or delay across all the shown output pins of the IC depends on the product of the values of R1 and C1, here pin 3 can be seen going after 32 logic pulses from pin 14 of the IC.

Identically you may find different equivalent rates at the other output pins of the IC. This timing proportion is observed when R2 and C1 are selected to be 10K and 0. When power is switched on via S1, a reset voltage is given to the IC through C2. Simultaneously the IC built-in oscillator starts providing pulses to the counter. Following clocks, the counter output Q14 goes high, turning on the oscillator across T1 and T2.

By doing this a sharp 3 kHz frequency that is emitted through an 8 ohm small loudspeaker. The circuit is powered down simply by turning off S1. With the indicated R2 and C1, the buzzer will sound approximately An hour after the circuit has been started up. By upgrading R2 with a 1 M adjustable potentiometer, the buzzer time period could be varied from 5 minutes to hours.

The potentiometer scale may be appropriately calibrated for quick setting up. The circuit utilizes hardly any current 0.

The furthest right bit represents 1, the next to the left represents 2, the next represents 4, the next 8, the next 16 and so on doubling every time you move one position to the left. Therefore is binary for 16, and is binary for With this knowledge, we can make a very accurate timer utilising our B binary counter chip. At that exact time we know that 16 seconds have elapsed. Just three external components are required to control the B counter — two resistors and one capactor.

Moogunos Thus a particular value of resistor, for fixed voltage, limits the current through it. This happens because we have connected pin 11 through a diode, oscillation stop and IC remains latched in high state until it resets. The set up can be modified or enhanced in many different ways for different applications. Timer Circuits With B A astable controlled by a watch crystal is accurate to a few seconds per month.
