and then uh the chip will send start connection and knows that which button is pressed. Suppose you have pressed channel one button , number one you have pressed , then the uh chip will know that the number one button was pressed.
It pros produces a mors morse code line signal specific to that button. Every button , every individual button , has its own morse code. Suppose uh the uh user has pressed butto button one , then it will have a spe the circuit will generate a specific morse code to b  that that button , and the transistor will amplify the signal and send then to the L_E_D_ which translates the signal into infrared light. Like  you have got a signal by pressing a button. That's a d a morse code has been generated by the integrated circuit. Now , that signal , that morse code , has to be amplified by the transistor. That is the use of transist transistor we  which we use in the remote controller. It will amplify the signal and it will send it to the L_E_D_ and which translates the signal into an infra infrared bits. The sensor on the T_V_ can see the infrared light , and seeing the signal seeing the signal re it reacts appropriately , that when it sees the amplified mo morse code signal , then it will uh it will uh know which uh what what action it has to uh do. Then it will do the appropriate action. So uh this is how the remote controller works.
It works.
Can you go to the next slide , please. Yeah , I have few pictures. When you look at the uh um remote controller uh it's it's  it  this is a normal remote controller. And  to the next slide , please.
