Arduino based GPS receiver. If you want to get alarm after every preset time interval, then remove this diode.
It is basically a 14 stage binary ripple counter and consists of an internal oscillator. Positive supply is given to pin Introduction We fd4060 been studying a lot about microprocessors and have taken a look at the architecture. In this you can select 7 different time intervals with the help of a rotary switch.
Each output goes high in the negative transition after the completion of one timing cycle. Relay Switch Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically. The resistor at pin 10 or the capacitor can be made variable, if the frequency is to be varied, otherwise fixed values may be chosen.

How IC is Wired as an Oscillator? Thus for example if the frequency at pin 3 is 1Hz, the frequency at pin 2 will be 2Hz, at pin 1 it will be 4 Hz ,at pin 15 it will be 8Hz and so on. So that counter will start again. A speaker is commonly used Pin 1 to 7 and 13 to 15 are the outputs of the IC.
Generally most ICs have a sunken circle just beside pin 1, otherwise it can be identified as follows:. The IC requires just a couple of resistors and a capacitor connected externally to start the oscillator.
In this position the pin beginning at the left of the notch is pin 1 and the pin ending at the right of the notch is pin It is necessary to add a capacitor close to pin 16 of IC so that minute voltage changes will not affect the timing cycle.
Let us see its complete working details. Outputs can give almost full supply voltage to drive light loads but output current is around 10 mA. Countdown timer using microcontroller AT89C Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically.

This happens because we have connected pin 11 through a diode, oscillation stop and IC remains latched in high state until it resets.
The basic frequency of the internal oscillator is determined by the value of the timing capacitor connected to its pin 9 and that of the timing resistor in its pin The oscillator can be stopped or reset by applying a logic 1 or a positive supply to pin 12 of the IC.
To get maximum time period, output Q11 is omitted in the IC itself so that double time is available between Q10 and Q Reset pin 12 resets the timing cycle once it is grounded. Its 16 pins are designated as follows: BC is an NPN bi-polar junction transistor.
Note that Q and Q11 are not available. The free ends of these components are all joined together. Its inbuilt oscillator is based on three Inverters. Alarm can be adjusted for duration of 30 seconds to 2 hour cd4006 minutes.
IC is an excellent integrated circuit for timing applications. Thus a particular value of resistor, for fixed voltage, limits the current through it.
Timer Circuit using IC CD 4060
Pin 9, 10, and 11 are reserved for the external frequency determining components. When counter reaches bit Q4pin 7 goes high so that the buzzer connected with the relay with the transistor turn on.
Interface GPS with Arduino. When the high output is connected to the pin 11 clock input through a cd44060, oscillation stops and IC remains latched in the high state till it resets. Ten of these fifteen signals are available on the output pins Q4- Q 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 internal oscillator of the IC can be made to oscillate just by connecting a couple of resistors to pin10 and 11 and a capacitor to pin 9.
Skip to main content. To solve this problem we have described a circuit below which gives an alarm after the preset time interval ci by you. 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.
