Re: New Infrared Remote Control Software

Beware of Differing Pinouts on Vishay IR Sensors.

There are different versions of the Vishay sensors in Identical packages.
The TSOP48xx family is one that works as documented with Gnd on Pin 2.
However, the TSOP322 family, which is arguably better because of its 2.7 - 5.5V power supply range, has ground on pin 3 and power on pin two. This is
reversed from TSPO48xx family.

IF YOU USE A TSOP322XX FAMILY SENSOR AND FOLLOW KEVIN'S DIAGRAM
YOU WILL INSTANTLY FRY THE SENSOR.

Good practice is to always make sure you have a datasheet for the actual
device you are using and double check the connections.
