      by magic?

      I found this answer on the web:
      The TV remote works by you pressing the buttons you want the TV to do; When the button is pressed it hits the circuit board, the chip can sense the connection in the circuit board, each button has a different code because of the different connections in the circuit board. It then translates the button into a sequence something like Morse code, amplified signal then travels to the LED. The LED transfers the signal in an infrared light to the TV. The TV then “sees” the signal and does what you originally told it to do
