Tutorial: How to use 3 Pieces TSOP4838 IC Integrated Circuits

The TSOP4838 ICs are used for infrared reception. Ideal for remote control and infrared interfacing projects.

What you need

• 3 pieces TSOP4838 IC
• Arduino
• Resistor (10kΩ)
• 12-pin connectors

Steps

1. 1. Ensure that the TSOP4838s are in good condition.
2. 2. Draw a circuit with 12 pins.
3. 3. Connect pins 1 and 2 to GND.
4. 4. Connect pins 11 and 12 to VCC (5V).
5. 5. Connect pin 6 to a digital pin on Arduino.
6. 6. Connect the resistor between pin 6 and GND.
7. 7. Upload the code to Arduino.
8. 8. Test the receiver with an infrared transmitter.

Example code

void loop() { if (digitalRead(6) == HIGH) { Serial.println("Ricevuto segnale"); } }

Mini project

Frequently asked questions

How can I verify if the TSOP4838s are working?
Connect pin 6 to a digital pin on Arduino and use an infrared transmitter.

Which pins should be used for communication?
Use pin 6 as an input pin.

Can I use an Arduino Mega?
Yes, but make sure the pin you use supports the digital function.
