What Are the Different Types of TV Remote Codes?

A TV remote control is a device used to remotely control machinery. Can realize the function of changing the TV channel. Modern remote controls are mainly composed of integrated circuit boards and buttons used to generate different messages. There is a computer called 'Central Processing Unit', which is called CPU in English. It is a computer for TV.

TV remote controls mainly rely on integrated circuits (also known as chips) to send instructions. The chip uses an 18-pin dual in-line package (DIP). To the right 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) next to the battery contacts. In this circuit, the chip can detect when a key is pressed. It then encodes the key information in a form similar to Morse code, and each key is encoded differently. The chip will send these signals to the transistor for amplification, making the signal stronger ^[1] .
