Projects using this component
Lighting 220V Bulb with Remote Control
Project that turns 220V light bulb on and off via relay with power and mute buttons of IR remote control. Combines infrared control with high voltage switching.
Laser Security System
Advanced security system that activates the alarm when the laser beam is interrupted and can be reset by push button or IR control. Teaches multiple input source and state management.
IR Receiver and Controller Value Reading
Project that reads the HEX values of infrared signals coming from the remote control with IR receiver module in Serial Monitor. Teaches the use of IRremote library.
Led On/Off with IR Receiver and Remote Control
IR control project that can independently turn on/off 3 LEDs with different keys of the remote control. Teaches how to match remote control codes and control multiple outputs.
Ready Melody Playback with IR Receiver, Controller and Buzzer
Project that plays Mario, Mother's Day and Christmas melodies with a buzzer by pressing different keys of the IR controller. It combines function triggering and melody programming with the controller.
Remote Control with ESP32 IR Receiver (with LCD Screen)
In this project, we use the TSOP4838 IR receiver module to capture signals from a TV, air conditioner, or any other infrared remote control using the ESP32. With the IRremote v4 library, we display and log the unique code for each button on the I2C LCD screen. We then use these codes to turn an LED on and off with the remote and adjust its brightness. This is a great starting point for converting old remotes into smart home controls.
ESP32 IR Universal Remote (IR Receiver + Remote Control + 3 LEDs + Buzzer + OLED)
With the ESP32, you can read a standard IR remote control and use it to control your own device! In this project, we use an infrared receiver (NEC protocol, 38 kHz) to capture the signals from a 20-button IR remote. We’ve defined different actions for each button: buttons 1, 2, and 3 toggle three separate LEDs; the PWR button turns them all off; and the numbers 4–9 display special characters on the OLED. The SSD1306 OLED display shows the last button pressed in large font, along with a descripti
