Updating the flip usb driver avr
This infrared remote library consists of two parts: IRsend transmits IR remote packets, while IRrecv receives and decodes an IR message.IRsend uses an infrared LED connected to output pin 3.You can find the script inside your IDE at the following path: shield upgrading script also make use of the dfu-programmer that you need to install on your system previously (make sure that the version is 0.5.4 or later).Connect a jumper on the J3 connector, that put the shield in the programming mode.On Windows, you need to install the AVR 32 Drivers .On Windows use the Flip software provided by Atmel to program the device using the DFU mode (Device Firmware Update).
Make sure the polarity of the LED is correct, or it won't illuminate - the long lead is positive.
Now you are able to download the firmware on the shield. On Linux and Mac we wrote a script that automates the process.
The script is a command line utility, so in order to use it you need to open a terminal on your system.
I used a NTE 3027 LED (because that's what was handy) and 100 ohm resistor; the range is about 15 feet.
For additional range, you can amplify the output with a transistor.
