The Linker base shield is installed on  a [bigcommerce link=”/cityduino-arduino-uno-compatible-device/” target=”_blank”]Arduino Uno[/bigcommerce]

Arduino Uno is connected to PC.

• +5V of the second Arduino Uno  – > +5 of Infrared Emitters and Detectors
• GND of the second Arduino Uno  – > GND of Infrared Emitters and Detectors
• D3 of the second Arduino Uno   – >  DIN of Infrared Emitters and Detectors

[/vc_column_text][/vc_tab][vc_tab title=”Test Code” tab_id=”1395235026500-2-4″][vc_column_text]The code of the receiver:

First download the corresponding IRremote library:IRremote

Then unzip the library under library directory of Arduino IDE:

Choose the example shown below and download the code into Arduino:

The code of transmitter:

#include "IRremote.h"

IRsend irsend;

void setup()
{
    Serial.begin(9600);
}

void loop() {
    Serial.println ("Begin test IR module!");
    irsend.sendNEC(0x9f8e7d6c, 32);
    delay (3000);
}

[/vc_column_text][/vc_tab][vc_tab title=”Test Result” tab_id=”1395235028705-3-4″][vc_column_text]Using a serial port terminal to open the COM port of the receiver:

We will observe that the receiver printing  9F8E7D6C  every 3 seconds.
When we stop  transmitting, the data will be in random noise.
