4.2.3. CRYSTAL OSCILLATOR
A crystal oscillator is an electronic component that uses the resonant
propertes of a piezoelectric crystal, to create an electrical signal with a
very precise frequency. Bot'n Roll ONE A uses a 16MHz quartz oscillator
crystal which makes the IC ATmega328 to operate at a 16MHz clock
frequency. Like traditonal watches, which also use a crystal, the usage of a
crystal makes the Bot'n Roll ONE A a very accurate machine to measure
tme.
On the printed circuit board serigraphy, the crystal
oscillator is represented by “XTAL”.
