What is Tk 1838
Tk 1838 is an infrared receiver module that consists of a photodiode, an amplifier, a demodulator, and an output stage. It can receive infrared signals with a carrier frequency of 38 kHz and convert them into digital pulses that can be read by a microcontroller. Tk 1838 has three pins: VCC, GND, and OUT. VCC is the power supply pin that requires 5V DC input. GND is the ground pin that connects to the negative terminal of the power source. OUT is the output pin that sends the digital pulses to the microcontroller.
What are the features of Tk 1838
Tk 1838 has several features that make it suitable for various applications. Some of these features are:
It has a low power consumption of about 0.4 mA.
It has a high sensitivity of about -90 dBm.
It has a wide operating temperature range of -25ÂC to +85ÂC.
It has a built-in filter circuit that can reject interference from ambient light sources.
It has a small size of about 6.4 x 6.4 x 5.1 mm.

How to wire Tk 1838 to Arduino
To wire Tk 1838 to Arduino, you will need the following components:
One Tk 1838 infrared receiver module.
One Arduino board (such as Arduino Uno).
One infrared remote control (such as TV remote).
Some jumper wires.
A breadboard (optional).
The wiring diagram is as follows:
The wiring steps are as follows:
Connect the VCC pin of Tk 1838 to the 5V pin of Arduino.
Connect the GND pin of Tk 1838 to the GND pin of Arduino.
Connect the OUT pin of Tk 1838 to any digital pin of Arduino (such as pin 2).
How to code Tk 1838 with Arduino
To code Tk 1838 with Arduino, you will need the following library:
IRremote: A library that allows you to send and receive infrared signals with Arduino.
The code example is as follows:
```c
// Define the pin that connects to Tk 1838
#define IR_PIN 2
// Create an IR receiver object
IRrecv irrecv(IR_PIN);
// Create a variable to store the decoded IR data
decode_results results;
void setup() {
// Initialize the serial monitor
Serial.begin(9600);
// Enable the IR receiver
irrecv.enableIRIn();
}
void loop() {
// Check if there is any IR data available
if (irrecv.decode(&results)) {
// Print the hexadecimal value of the IR data
Serial.println(results.value, HEX);
// Resume the IR receiver
irrecv.resume();
}
}
```
This code will print the hexadecimal value of the IR data that is received by Tk 1838 on the serial monitor. You can use this value to identify the button that is pressed on the remote control. For example, if you press the power button on your TV remote, you may see a value like FFA25D. You can then use this value in your code to perform different actions based on the button pressed.
