  4. Remote
  5. Jumper wires

What is IR Receiver module?

The IR receiver modules (such as TSOP38238) can receive signals from the IR remote control. These modules typically consist of VCC, GND, and an output pin.

Working:

  1. Signal Transmission:
  • IR Remote:

When you press a button on the IR remote control, it emits infrared light containing a unique code for each button.

  1. Signal Reception:
  • IR Receiver:

The ESP32 is connected to an IR receiver module that detects the infrared light signal from the remote.

  • Electrical Signal:

The IR receiver translates the infrared signal into an electrical signal readable by the ESP32.

Circuit Connections:

  • Connect the VCC pin of the IR receiver to a 3.3V pin on the ESP32.
  • Connect the GND pin of the IR receiver to a GND pin off ESP32.
  • Connect the output pin of the IR receiver to any digital pin of ESP32.

Usages:

The interfacing of an IR remote with an ESP32 opens up a range of practical and fun applications:

Home Automation:

  • Controlling Devices: Use the IR remote to control lights, fans, or appliances connected to the ESP32. Turn them on/off or adjust settings remotely.

Entertainment Systems:

  • Media Center Control: Manage media players or TVs by using the remote to play, pause, or change content.

IoT Projects:

  • Smart Home Integration: Incorporate IR remote control as a part of a larger IoT system to interact with various smart devices.

Robotics:

  • Robot Control: Employ IR remote commands to control robot movements or actions wirelessly.

Educational Projects:

  • Learning Tool: Use IR remote interfacing as a way to teach about sensors, communication protocols, and microcontroller functionality.
