Receiving and Decoding IR Using an Infrared Library on
Finally you will need an IR remote such as you use for controlling your TV, cable box, or DVD player. All of our examples will use the Adafruit Mini Remote Control shown on the right however we will show you how to detect what protocol your own TV remote is using and if it is a protocol supported by IRLib you can use it instead.
7 segment Display and Driving a 7 segment Display
This BCD to 7 segment decoder/driver takes a four bit BCD input labelled A, B, C and D for the digits of the binary weighting of 1, 2, 4 and 8 respectively, has seven outputs that will pass current through the appropriate segments to display the decimal digit of the numeric LED display.

How to Control A 4 Digit 7 Segment LED Display Using Phidgets
Using his transistor method significantly reduces the number of Phidget slots for a 5 digit display versus traditional method of wiring a collection of single digit LEDs, each digit using up to 8 Phidget slots. What You Need: • Phidget LED 64 board (with power supply and USB cable) • a common anode multiplexed 7 segment LED (up to 5 digits)
Sending IR Codes Using an Infrared Library on Arduino
IRLib not only receives and decodes IR signals but it can transmit them as well using an IR LED and a driver circuit. The library has been used to control TVs, cable boxes, DVDs, VCRs, and IR controlled toys such as helicopters and dinosaur robots. It could also be used to control
