IAKO NAŠ ARDUINO IMA SVEGA 13 DIGITALNIH I 5 ANALOGNIH IZLAZA KORIŠTENJEM TEHNIKE MULTIPLEKSIRANJA MOŽEMO KONTROLIRATI 64 LED DIODE U OVOJ MATRICI
Arduinom možemo kontrolirati matricu od 64 LED diode korištenjem 16 pinova. LED diode povezane su u matrici tako da svaki od izvoda na matrici kontrolira ili jedan reda ili jedan stupac matrice.
To znači ako želimo na matrici uključiti krajnje lijevu LED-icu u prvom retku moramo na pin 9 matrice dovesti pozitivni napon( +5V) a na pin 13 matrice GND (0V).
Upozorenje: Kao što znamo, bilo koju LED diodu koju spajamo na Arduino moramo u seriju spojiti s otpornikom kako bi pinove Arduina zaštitili od prevelike struje (>50mA ) koja bi uništila pin.
Prilikom spajanja matrice na Arduino na sve pinove koji predstavljaju redove (9,14,8,12,1,7,2,5) postaviti ćemo otpornike (vrijednosti između 200 i 400 ohma).
