Arduino uno User Manual

What You Need
1. One or more infrared remote controls. They can be from your TV set or
your DVD player, for example.
2. An Ethernet shield for the Arduino.
3. An infrared receiver, such as the PNA4602 or the TSOP38238.
4. A 100Ω resistor.
5. An infrared LED.
6. Some wires.
7. A breadboard.
8. An Arduino board, such as the Uno, Duemilanove, or Diecimila.
9. A USB cable to connect the Arduino to your computer.
Understanding Infrared Remote Controls
To wirelessly control a device such as a TV set, you need a sender and a
receiver. The receiver usually is built into the device to be controlled, and the
sender is part of a separate remote control. Although you can choose from a
variety of technologies, such as Bluetooth or Wi-Fi, most modern remote
controls still use infrared light for communication.
Using infrared to transmit signals has several advantages. It is invisible to
human beings, so it won’t bother you. Also, you can generate it cheaply with
infrared LEDs that can be integrated easily into electronic circuits. So, for
