Help me, how to add a library to the arduino, I want to add i2c lcd library

Nick_Pyner

I believe there is some specific instruction on this on the Arduino website, but I just put it with all the other libraries. This is in a folder under the 1.0.1 IDE. \libraries..

You need to restart your IDE after you install one for it to see the new one.

The currently recommended procedure for installing extra libraries is explained here --> http://arduino.cc/en/Guide/Libraries <-- .

If you do it the way Nick mentions, which will indeed work, you then must remember to reinstall the library whenever you upgrade to a newer Arduino release.

In either case you have to restart the IDE as Mike mentioned.

patra,
After at least Arduino1.0.1 the LiquidCrystal_I2C library is included.
If you do download one be sure to use this https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads. It is the same one used by the official release and is faster and more complete than any other. Thanks go to FM for his outstanding work. There are complete instructions included in the .zip. If you do put it in the Arduino sketchbook /librariesfolder (recomended) makes  sure you find the actual Arduino program folder, go to the libraries folder there and move the old LiquidCrystal library to a completely different location or delete it entirely.  Two libraries with the same name will cause conflicts.
