photo resistor

These are useful for Arduino compatible boards that don’t come with headers already installed (like the Arduino Pro)

and a single RFP30N06LE MOSFET

If you are not comfortable doing this

This allows for universal low-voltage bidirectional translation between any of the 1

SparkFun Sound Detector Audio, Sound, Sparkfun Originals Maternity photo resistorThe SparkFun Sound Detector is a small and very easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneous and independent, so you can use as many or as few as you want at once. The envelope output allows you to easily read amplitude of sound by simply measuring
