Lesson 21/31: Using Infrared Remote Control with Arduino | SunFounder Robojax

In this lesson, we learn how to detect signals from an infrared (IR) remote and take action based on the input. We use both an IR receiver and transmitter for this tutorial. First, we install the necessary library and demonstrate how to press a key on the IR remote to view the corresponding output on the Serial Monitor. Next, we identify specific keys and program actions, such as turning a buzzer ON, in response. The lesson includes a complete explanation of the code, detailed wiring diagrams, and a thorough explanation of the wiring setup.
