Prot = Protection Diode 1N4005
NPN = N2222 General purpose transistor amplifier
SENS = Sensitivity set by an adjustable trimmer resistor
TIME = Same as SENS, exep thisone controls how long the motor spins
the 220n is a disk capacitor
I drew the diagrams on the computer by looking at the prototype, so they are not very easy to understand, if anybody has more questions, post or PM me.
