OVERVIEW:The Arduino Pro Mini is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. A six-pin header can be connected to an FTDI cable or Spark..
OVERVIEW:A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency.This frequency is commonly used to keep track of time (as in quartz wristwatches), to pro..
