WebEen LED Matrix bestaande uit 4 kleinere LED matrices. Specificaties: Voedingsspanning: 5V DC Signaalspanning: 5V Driver: MAX7219 Resolutie: 32 x 8 pixels Pixelkleur: Rood … WebUvod. Zabaven način za izdelavo majhnega prikazovalnika je uporaba 8×8 matrike ali 4-mestnega 7-segmentnega prikazovalnika. Takšne matrice so “multiplexirane” – za nadzor 64 LED diod potrebujete 16 pinov. To je veliko pinov in obstajajo gonilni čipi, kot je MAX7219, ki lahko nadzorujejo matriko namesto vas, vendar je potrebna veliko ...
