Piezo Vibration Sensor

Hi there, I am very very new to electronics in general and hoping to work on a project with the arduino and some vibration and light sensors.

I was wondering if there was an affordable kit I could buy that will allow me to monitor what each sensors is actually doing? From my understanding, most of these sensors produces a current when triggered, in this case a vibration or light, but different level of vibration or brightness would produce different voltage, would a simple volt meter do the job? Or are there more specified kit? Find it quite difficult to work on these sensors as I'm not really getting any feedback, can't easily tell if they are working or how to monitor the intensity, thank you!

Sounds like you need an oscilloscope.
check out www.dpscope.com, I use this when I am debugging and want to see what signals are doing.

From my understanding, most of these sensors produces a current when triggered, in this case a vibration or light...

This depends on what sensors you have; solar panels will produce a current when light hits it, whereas a photoresistor (aka Light Dependant Resistor or LDR) will change it's resistance depending on the amount of light energy. I just thought you should know that for future reference :). By the way, CrossRoads is right.
