Hisense Smart Tv Remote Control

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.
