INFRA-RED REMOTE CONTROL USING NE555

  INFRA-RED REMOTE CONTROL USING NE555
Hello visitor, how are you? Of course you are happy, because technology lovers never spends a dull moment, today make your moment more interesting,
It is a very simple way to make IR remote control.
Let’s see which components will require-
One NE 555 timer ic
One IR sensor/receiver
Resistors- 20k,
capacitors-10uf,1uf,0.1uf
one 6 volt battery

circuit diagram-
remote control using NE555
the project I made-
How it works?
The infra red sensor takes the signal from a remote, the pulse is then fed to the trigger input on NE 555 timer, here the circuit is in bi-stable mode, as soon as you press any button of your remote, the transmitted pulse is received by a  receiver, and the 555 makes it’s output pin (pin no 3)
On,
If we connect a led in the pin no 3, when we press the remote, we can see the LED is on,
