Timer Circuit using IC CD 4060

These are generically known as supervisory chips when supplied in monolithic form. Relay is an electromagnetic device which is used catasheet isolate two circuits electrically and connect them magnetically. Arduino based GPS receiver.

Choosing Battery for Robots. Internally the oscillator signal is applied to the first bistable which drives the second bistable and so on.

Is a B IC meant to start with Logic 1 on outputs, or does it datashwet counting from 0? When counter reaches bit Q4pin 7 goes high so that the buzzer connected with the relay with the transistor turn on.

This happens because we have connected pin 11 through a diode, oscillation stop and IC remains latched in high state until it resets. Its inbuilt oscillator is based on three inverters. datasueet

When an electric signal is dayasheet to the input pin of speaker, it generates sound waves. If you followed the rules in the datasheet. 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.

Here is a typical example of a chip that might be suitable 40600be a 5V supply not a recommendation of this particular Maxim part. This compatibility flaw is when the designer learns to follow standard practice of a separate discrete Power On Reset controlled starting condition for all bistable logic to prevent POR race conditions or other undesirable characteristics.

Interface GPS with Arduino. I do recall having Pin 12 connected straight to ground, however I guess I must use a capacitor and resistor in series. So that counter will start again. Image below shows the pin layout of the IC: Then the next clock edge is determined by R1C1 time constant so R2C2 determines the latency needed to let power up stabilize. A loudspeaker or “speaker” is a transducer that 4060bs electrical energy into acoustical energy.

Surely as its a binary counter, its meant to start with all outputs on logic 0, and count up using binary? It is important to connect pin datashete reset pin to ground for enabling the IC to oscillate and we have connected it to positive supply.

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.

A speaker is commonly used Now we can connect other output also with the rotary switch to get different time period.


When power is ON, the pulse at the junction R1 and C2 resets the counter and counting starts. 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. 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 Thus a particular value of resistor, for fixed voltage, limits the current through it.

Show me me your Vcc on power up and your schematic and layout and I will tell you why it happens to you and how to prevent it with POR or other methods.
