Lolenge ya kosalela display ya ba segments 7

Lolenge ya kosalela display ya ba segments 7

Na boyekoli oyo, tokotalela ndenge ya kosalela display ya ba segments sambo (7-segment display) na ndenge ya malamu, tokotalela mingi bokeseni kati na common cathode mpe common anode. Mokambi oyo akosalisa yo kososola ndenge ya kosangisa display, koyeba ba résistances oyo esengeli, mpe kokamba ba segments mpo na kolakisa ba chiffres na ndenge ya malamu.

Ba displays ya ba segments sambo bazali na ba LED mwambe, oyo babongisami mpo na kosala ba nombres mpe ba symboles na kopelisa ba segments oyo esengeli. Ba segments yango babengami A kino G, elongo na segment mosusu mpo na point ya décimal (DP). Kolandela ndenge ozali kosalela display ya common cathode to common anode, ndenge ya kosangisa mpe contrôle ekokoma kokesene mingi.

Mpo na kososola malamu lisusu projet oyo, tala vidéo oyo elandi mpo na ba explications ya visual (na vidéo na 0:00).

Matériel oyo esengeli

Ba composants ya minene ya projet oyo ezali display ya ba segments sambo, ba résistances, mpe microcontrôleur lokola Arduino. Display ya ba segments sambo nde ezali outil ya liboso oyo elakisaka ba nombres na kopelisa ba segments oyo esengeli.

Ba résistances ezali na tina mingi mpo na kokanga courant oyo elekaka na segment moko na moko ya LED mpo na kopekisa yango kobeba. Microcontrôleur etindaka ba signaux na ba pins ya display mpo na kokamba ba segments oyo esengeli kopelisa, mpo na kolakisa ba nombres ndenge na ndenge. Kososola ndenge ya configuration ya display na yo (common cathode to common anode) ezali na tina mingi mpo na kosangisa na ndenge ya malamu.

Ba Détails ya Datasheet

• Salela résistance moko na segment moko mpo na kokamba courant.
• Valeur ya résistance ya momesano: 140 ohms mpo na alimentation ya 5 V.
• Kokamba na ndenge ya malamu kolandela ndenge ya display.
• Meka segment moko na moko mpo na koyeba soki ezali kosala.
• Talá ba ratings ya tension ya liboso mpo na kopekisa kobeba.

Ba Instructions ya Kosangisa

Mpo na kosangisa display ya ba segments sambo, banda na kosangisa pin ya commune (common anode to common cathode) na source ya courant oyo esengeli. Mpo na display ya common cathode, sangisa pin ya commune na terre. Mpo na display ya common anode, sangisa yango na source ya tension ya positif.

Démonstration / Nini Okomona

Soki esangisami mpe programé na ndenge ya malamu, display na yo ya ba segments sambo esengeli kopelisa ba segments oyo esengeli mpo na kolakisa ba nombres oyo olingi. Na ndakisa, mpo na kolakisa nombre 1, esengeli sé ba segments B mpe C bapelisa. Tala malamu polarité ya ba connexions na yo, pamba te kosangisa commune na ndenge ya mabe ekoki komemela mpe kozanga kosala malamu to kobebisa display.
