Building an IR receiver device is intuitively easier and will be our first step towards learning IR communications using Arduino. For building a basic Infrared receiver device we will use the following parts:
- One Arduino Uno R3
- One USB cable
- One IR receiver (TSOP family of IR receivers)
- One pc. 1K Ohms resistor
- Some male-to-male jumper wires
In the following sections, we will see examples of two popular IR receivers from the TSOP family of IR receivers and the SM0038 IR receiver. The IR receivers have in-built circuitry for receiving and decoding the IR signals. No additional circuitry is required for decoding the received IR signals. All you need to do is plug in the proper breadboard connection with the Arduino.
The first example will be a detailed example. We will use the TSOP1738/TSOP1838 IR receiver to build an Arduino-based device to...
