Simplifying IR Remote Processing

Tauntek has a chip (18-pin Microchip® PIC 16LF87) that receives and processes IR remote signals. It is called "TinyIR2". It receives the IR signals and outputs a signal (e.g. a pulse) in its outputs. The chip costs $8 and has the following features

• Learning - Use it with a remote you already have
• Output signals are usable directly - 12 pulse or level outputs are availabl. By installing a few external passive components you can configure 0, 2, 4, 6, 8, 10, or all 12 of the outputs as momentary, and the rest as toggle. Toggle outputs change state when their command is recognized.
• Three different pulse widths available. 100, 500, or 1000 mSec (selectable)

With this chip, there is no need to decode the IR signals. All that is needed is to connect each output pin to an interrupt pin in the Arduino.
