I'm new to Arduino and I'd like to realize a system using Arduino One and SparkFun Electret Microphone Breakout (BOB-09964) to turn on/off lights clapping my hands. https://www.sparkfun.com/products/9964
What are the components I need? I'm going to buy them and I don't want to buy components which I will not use soon (so no starter kits but only a breadboard, resistors, LEDs, etc...).
Sorry for this basic question but as I said I'm new to this world.
