Software
Supply power to the obniz and run the program. The temperature measured by temperature sensor will be displayed.
Second, record your air conditioner’s signal for ON/OFF.
The example contains comment outed code for IR receiver. Remove the comment out and record your air conditioner’s ON/OFF signal. Your signal will be showed in log.
Put recorded data into the array of the infraredLed.send([]) at the “Program”(line 23).
$("#on").click(function(){
// your value for ON here.
infraredLed.send([])
})
$("#off").click(function(){
// your value for OFF here
infraredLed.send([])
})
At last, run the program again and push tap the “ON/OFF” button.
