Tutorial: How to use TSOP2236 IC Integrated Circuits

The TSOP2236 is an infrared receiver used to detect IR signals from remote controls or sensors. Ideal for home automation projects and Arduino prototypes.

What you need

• Arduino Uno
• Remote control
• Wired connection

Steps

1. Connect the TSOP2236 pins to the digital pins of the Arduino.
2. Check the power supply voltage of the device on the datasheet to ensure proper operation.
3. Write an Arduino sketch that reads from the pin connected to the TSOP2236.
4. Test the system by sending IR signals from the remote control and observe if the data is received and displayed in the Arduino IDE.

Example code

void setup() {
 Serial.begin(9600);
}

void loop() {
 if (digitalRead(pin_di_rilevazione) == HIGH) {
 Serial.println("Segnale IR ricevuto");
 }
}

Mini project

Create a home control system that turns on or off a light when the corresponding button on a remote control is pressed.

Common mistakes

• Do not verify the power supply voltage required for the TSOP2236.
• Connect the device pins incorrectly.
• Omit the testing phase with a real remote control.

Recommended accessories

• Arduino Uno
• Universal Remote Control
• LED and resistor

Frequently asked questions

Does the TSOP2236 work only with Arduino?
No, it can be used with any circuit that has a digital pin.
