1 x 1602 LCD ekraan

Kujutiste kuvamine toimub 8-baitiste järjendite abil, kus iga baidi 5 parempoolset bitti defineerivad ühe pikslirea. Järgnevas koodiplokis on toodud CustomCharacker koodist inspireeritud liikuva pildi kood.
Tulemuseks on liikuv pilt, kus poiss ja tüdruk üksteiseke südameid ja naerunägusid saadavad.
