38KHz Infrared Transmitter Module KY-005

Description

What is it The 38KHz Infrared Transmitter Module KY-005 is an electronic component designed for infrared communication. This device is suitable for various Arduino projects to control electronic devices. Features Type of module: Infrared Transmitter KY-005 Operating frequency: 38KHz What is it used for Infrared transmitter modules are used to create remote control systems. For example, they can be integrated into an automatic lighting system where the KY-005 is connected to an electrical switch to turn lights on or off based on received infrared signals. Tutorial: How to use KY-005 The 38KHz Infrared Transmitter Module KY-005 is ideal for controlling infrared-enabled devices. Useful for beginners and intermediate designers. What does it need Arduino 1kΩ Resistor Power Supply Ground Cable Steps 1. Connect the 1kΩ resistor between VCC and GND of KY-005. 2. Connect VCC of KY-005 to 5V of Arduino. 3. Connect GND of KY-005 to GND of Arduino. 4. Connect the S (signal) pin of KY-005 to a digital pin of Arduino. 5. Upload the following code. 6. Test the transmitter with an IR receiver. 7. Check the datasheet for further details. 8. Adapt the code for your project. Example Code “` int ledPin = 9; void setup() { pinMode(ledPin, OUTPUT); } void loop() { digitalWrite(ledPin, HIGH); delay(1000); digitalWrite(ledPin, LOW); delay(1000); } “` Mini-project Create an automatic lighting system: connect the KY-005 to an electrical switch to turn the light on/off. Common errors Not checking the datasheet. Connecting VCC to 3.3V instead of 5V. Omitting the 1kΩ resistor. Connecting the S pin to GND instead of a digital pin.
