  • include <IRremote.h> Use infrared library function
  • IRsend irsend; Define infrared receiving object
  • irsend.sendSony(0xa90, 12); Send infrared code
  • You can open the serial monitor. Input any values at the console and you'll see the LED on the IR-transmitter blinks once, meaning the infrared signal has been sent.
