Outline

Microduino-IR-Transmitter can emit infrared signal through LED and then receive signal with Infrared receiver. Like a remote controller, the infrared transmitter can also control home appliances such as TV, air conditioner, water heater and refrigerator. Its maximum transmission distance is 10m.

Specification

Development

Equipment

Preparation

Setup 1：Connect the IR transmitter's interface with the Hub's D6 digital port.

• Setup 2：Connect the core, Hub and IR transmitter to a computer with a USB cable.

Debugging

• Open " IRsendDemo " program in the libraries.

• Select the right board and COM port, compile and download. You can refer to AVR Core：Getting started

• 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.
