infrared ir wireless remote control module kit

infrared (IR) wireless remote control module kit typically includes a slim, handheld 17-to-20-button IR transmitter remote (powered by a CR2025 coin cell battery), a 38kHz IR receiver module, and jumper wires. It is widely used with microcontrollers like Arduino and Raspberry Pi for DIY robotics and home automation. 

• Operating Voltage: 3.3V to 5V DC
• Carrier Frequency: 38kHz (standard modulation for IR signals)
• Transmission Range: Up to 8 meters (line of sight)
• Effective Angle: Approx. 45° to 60°
• Key Count: 17 or 20 function buttons

Pin Connections

• GND: Connects to ground on your board
• VCC: Connects to 3.3V or 5V power
• DAT / Signal: Connects to a digital input pin (e.g., Pin 11 on an Arduino) 

How to Use with Arduino

• Install the IRremote library through the Arduino IDE.
• Wire the receiver module to power, ground, and a digital pin.
• Upload a basic scanning sketch to read the unique hexadecimal code assigned to each button press on the remote.
• Map those decoded hexadecimal values in your code to trigger actions like turning on an LED, moving a robot motor, or toggling a relay.
