Welcome to the next tutorial of our raspberry pi 4 programming course. The last guide covered connecting a Sharp infrared distance measurement sensor to a Raspberry Pi 4. Infrared (IR) sensors were demonstrated to be widely used for nearby object recognition and motion tracking. But in this session, we'll utilize Raspberry Pi 4 to create a radio-frequency (RF) remote control that can be used to operate the gadgets wirelessly. With the help of this RF remote control, we can Power On/Off the devices.
