Mainly rely on the TV remote control integrated circuit (also known as chips) to send commands, the chip uses a 18-pin dual in-line package (DIP package abbreviated DIP). On the right side of the chip, you can see a diode, a transistor (black, three pins), a resonator (yellow), two resistors (green) and a capacitor (dark blue). Next there is a battery in the contact resistance (green) and a capacitor (small brown discs). In this circuit, the chip can detect when a key is pressed.
