Television
remote controller is a device used for remote control of machinery. It
can realize the conversion of TV channel and other functions. Modern
remote controllers are mainly composed of integrated circuit boards and
buttons used to generate different messages. Inside, there is a computer
called CPU, which is called CPU in English. It is a computer of TV
set.Inside is a computer called CPU, which is called CPU in English. CPU
input all kinds of menu password information of TV when it is
manufactured. The remote control transmitter of TV can realize the
remote control of TV only by issuing the corresponding
password.Television remote controller mainly relies on integrated
circuits (also known as chips) to send instructions. The chip uses
18-pin dual-in-line packaging (DIP). On the right side of the chip, you
can see a diode, a transistor (black, with three pins), a resonator
(yellow), two resistors (green) and a capacitor (dark blue). There is
also a resistor (green) and a capacitor (small brown disc) beside the
battery contacts. In this circuit, the chip can detect when a key is
pressed. Then, it encodes the key information in the form of Morse code,
and the codes of each key are different. The chip sends these signals
to the transistor for amplification to enhance the signal.
