Need Help

I would like to know what kinds of electronic accessory should I buy when I only have a Arduino board.
I may have to use these to have control of temperture,force,moment,light intensity and so on......

A LCD Module ( 2x16 or 4x20 ) would be a great addition to your Arduino as you can output the display to the LCD instead of using Serial to monitor the output..

A Protoshield + mini breadboard is the 2nd useful accessories as you can do your prototype on it and some version have like 5 Vcc and % Ground pins on the side...

Jumper cables, lots of male-male jumper cables!!!!

I've wrote an Arduino blog for beginners, located at the WWW links below...
