Story
Working
This example uses IR Receiver to receive code from any IR remote. After every IR code received next use case will run on IdIotware shield. Sequence of use cases : RGB color effects,Happy birthday melody on buzzer, police siren, display current temperature on OLED.
We are using LM35 temperature sensor to monitor the temperature.The idIoTware shield has a built in, on board, lm35 sensor.
On the idIoTware shield, the LM35 , temperature sensor is wired such that with a higher temperature we get a higher Analog Voltage on PIn A0.
The Following function is used to display the temperature on the idiotware shield. If button is not pressed on the remote control ,the oled screen will keep showing the temperature .
float temperature()
{
// return degreesC;
u8g.firstPage();
do
{
u8g.drawStr(5,20,"Temperature:");
//u8g.setFont(u8g_font_timB18);
u8g.setPrintPos(15, 42);
u8g.print(tempInC );
u8g.setPrintPos(59, 42);
u8g.print(char(176));
u8g.setPrintPos(67, 42);
u8g.print("C");
} while( u8g.nextPage() );
// rebuild the picture after some delay
// delay(50);
Similarly other functions are invoked .When We press the button on IR remote this statement “(irrecv.decode(&results) “ decodes the IR signal and then the sequence of use cases start getting executes.

Once you upload the code you can now use remote control to control Sequence of use cases.The other application’s include, is to control your robot build from idiotware shield with any IR remote or you can also make smart plugs that will turn on or off with just IR remote.
