Infrared transmission

Outline The Microduino IR LED can emit infrared signals just like a remote control. Couple this with an infrared receiver and you can control projects from a distance. The maximum transmission distance for the emitter is 10 meters. Specification Electrical Specifications Operation Voltage: 3.3V~5V This is an Output Device Technical Specifications Emitting Distance: 10 meters Emitting Angle: 25 degrees Wavelength: 940nm Dimensions LED: 5mm Board: 10mm x 20mm Connector: 4-Pin, 1.27mm-pitch Connector Interface Pins: D6 (on Hub), VCC (power), GND (ground) and NC (Not Connected) NOTE: To emit at the proper frequency for remote control (38KHz), the sensor must be connected to pin D6 on the Sensor Hub Development Equipment Module Number Function mCookie-CoreUSB 1 Core board mCookie-Hub 1 Sensor pin board Microduino-IR Transmitter 1 Infrared transmission 600px Preparation Setup 1: Connect the IR transmitter's interface with the Hub's D6 digital port. 600px 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> - Imports the IRremote library and allows you to use all functions. IRsend irsend; - Declares an object for the infrared transmitter to use IR functions. irsend.sendSony(0xa90, 12); - Sends an infrared code using a Sony remote protocol. Once you open the Serial Monitor, you can input any values into the console. The LED on the transmitter will blink once the infrared signal has been sent.
