Test Result

Done uploading the code to the board, the power led 2 is normally on, open the serial monitor and set the baud rate to 9600.
Aimed at the IR receiver, press the buttons on IR remote control, you should see the decoding value of button is displayed on the monitor.
Do not press too long, or else appear the data error like FFFFFF.


If press the SW1 button, passive buzzer beeps and then RGB LED will emit the red, green and blue light in sequence. Also the red led3 and blue led 4 light up, circularly.


If press the SW2 button, passive buzzer stops beeping and LEDs not light.
Then open the serial monitor and set the baud rate to 9600. Press the SW2 button again, the serial monitor will display the data shown below.


From the data shown on the monitor, you can get the details as follows:

• The first column is status OK.
  
• The second column is the humidity value measured by DHT11 sensor;
  
• The third column is the temperature value measured by DHT11 sensor;
  
• The fourth column is the analog value measured by potentiometer, in the range of 0-1023;
  
• The fifth column is the analog value measured by photocell. The stronger the light is, the greater the value is.
  
• The sixth column is the analog value measured by LM35 temperature sensor, which can be used to calculate the specific temperature value.
