It is important to connect pin 12 reset pin to ground for enabling the IC to oscillate and we have connected it to positive supply. This is done so that it instantly stops the IC from oscillating and resets it back to its original stage. For example suppose initially the pin is connected to the ground for enabling the IC to oscillate let say for 5 minute, connecting the pin to the positive would immediately halt the counting after 5 minutes and reset it back to zero.
So that counter will start id. Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically. Its resistance is given by the ratio of voltage applied across its terminals to the current passing through it.
Thus a particular value of resistor, datazheet fixed voltage, limits the current through it. They are omnipresent in The charge q stored in a capacitor is the product of its capacitance C value and the voltage V applied to it.
Capacitors offer infinite reactance to zero frequency so they are used for blocking DC components or bypassing the AC signals. When an electric signal is applied to the input pin of speaker, it generates sound waves.
The other pin is connected to ground. A speaker is commonly used This high-density System-in-Package SiP integrates controller, power switches, and support components. Skip to main content.

Several times we forget to switch off the gas, electric oven, stove datashewt motor while watching TV or taking on the phone or while talking to a friend in your neighborhood. To solve this problem we have described a circuit below which gives an alarm after the preset time interval selected by you.
In this you can select 7 different time intervals with the help of a rotary switch. Therefore after a preset interval of time it will give a loud alarm and reminds you that you have to off your machine or gas. The timer circuit is built around the CD which is 14 stage ripple carry binary counter, divider and an oscillator. Image below shows the pin layout of the IC: Here, IC1 works as frequency divider circuit. Its inbuilt oscillator is based on three inverters.
The basic frequency of the internal oscillator is determined by the value of the capacitor connected to its pin 9 and the resistor connected to pin By increasing or decreasing the value of capacitor and resistor, we can change the time delay for the period of on and off. Internally the oscillator signal is applied to the first bistable which drives the datashwet bistable and so on. Since each bistable divides its input signal by two, a total of fifteen signals are available, each of half the frequency of the previous one.
Note that Q and Q11 are not available.

Alarm can be adjusted for duration of 30 seconds to 2 hour 30 minutes. Here we have used a rotary switch to select the time required. When power is ON, the pulse at the junction R1 and C2 resets the counter and counting starts. When counter reaches bit Q4pin 7 goes high so that the buzzer connected with the relay with the transistor turn on. Similarly if you have connected the rotary switch to pin 5, then at this time Q5 gives 32 divisions and it will give an alarm after 30 seconds and continue to give alarm until you switch off the alarm externally.
This happens because we have connected pin 11 through a diode, oscillation stop and IC remains latched in high state until it resets. If you want to get alarm after every preset time interval, then remove this diode. Now we can connect other output also with the rotary switch to get different time period.
