on video A Simple Timer Circuit Diagram with IC 555
Here, in this article, we are going to see the circuit diagram of a simple timer built with IC 555. We know the IC 555 is a timer IC that is easily available in the market and it is very easy to use also. So you can easily make a timer circuit by connecting a few electronic components with the IC.
First of all, let's see the circuit diagram.
Circuit Components
9V DC Power Source or you can use a battery
1Pcs 10K Resistor
1 Pcs NO Push Button Switch
A 1 Mega Ohm Potentiometer or Preset
At 16V, 1000uF Capacitor
An IC 555 Chip
An LED to check the circuit output or you can use any other devices (such as Buzzer) or connect with other circuits.
Login Procedure
Connect pin 8 of the IC to the positive terminal of the power supply.
Connect pin 1 of the IC to the negative terminal of the power supply.
Connect one side terminal of the preset to the positive terminal of the power supply.
Short the middle terminal and another side terminal of the preset and connect them to pins 6 and 7 of the IC by shorting them.
Connect the 1000 uF capacitor between the 6 no pin of the IC and the negative terminal of the power supply. Connect the negative terminal to the negative terminal of the power supply and the positive terminal to the 6 no pin of the IC.
Connect a 10K resistor between the positive terminal and negative terminal of the power supply.
Connect one terminal of the push button switch to pin no 2 of the IC and another terminal to the ground or negative terminal of the power supply.
Connect pin no 4 of the IC (Reset terminal) directly to the positive terminal of the power source.
Connect the positive terminal of the load(here is the LED) to the positive terminal of the power source and the negative terminal to pin no 3 of the IC(it is the output terminal).
