In this post I'll experience with three kind of components available in the Arduino Base Workshop KIT: diodes (model 1n4007), transistors (models BC547 Transistor and MOS Irf540) and optocouplers (model 4N35). I'll briefly describe them and we'll see some simple examples of circuits built upon an Arduino Duemilanove board which make use of them.
