IR Remote Control w/ NEC Encoding & 38KHz Carrier

This remote uses the standard NEC protocol. To decode signals with an Arduino, connect an IR receiver module (like a TSOP38238) to a digital pin, then use the popular IRremote library. The library's `IRrecv` class will capture the raw timing data, and the `decodeNEC()` function will parse the 16-bit custom code (00FF) and 16-bit command data for each button press, allowing you to map actions in your sketch.

This remote requires one standard 3V CR2032 coin cell battery, which is not included due to shipping restrictions. To install, locate the battery compartment on the back of the remote, use a small tool to open the cover, insert the battery with the positive side facing up (typically marked on the compartment), and then securely close the cover. Ensure the battery is fresh for optimal range and performance.

No, this remote is hardcoded to transmit only the NEC protocol with a fixed user code. It cannot be reprogrammed to emulate other protocols like Sony SIRC or Philips RC-5. It is compatible only with devices or IR receiver modules that understand the 38kHz NEC format. For controlling devices with other protocols, you would need a programmable IR blaster or a different remote.

The remote is specified to work at distances greater than 8 meters under typical line-of-sight conditions with fresh batteries. It features a wide beam angle of up to 60 degrees, meaning you do not need to point it directly at the receiver for it to work reliably. Performance can be reduced by strong ambient light (sunlight) or physical obstructions between the remote and the IR receiver sensor.
