Saukewa: AVT1853-RGB
Makullin ga ƙungiya mai nasara ba kawai kiɗa mai kyau ba ne, har ma da haske mai kyau. Tsarin direba na RGB LED wanda aka gabatar zai gamsar da tsammanin har ma da mafi yawan masu neman jam'iyyar.
An nuna zane-zane na RGB illuminophony a cikin Hoto 1. Ya ƙunshi microcontroller, amplifier aiki da transistor wuta. Ana ciyar da siginar shigarwa ta capacitor C1 zuwa shigar da amplifier mai aiki. Ƙimar shigar da son kai ana ƙaddara ta mai rarrabawa da aka gina daga resistors R9, R10, R13, R14. Microcontroller (ATmega8) yana rufewa ta hanyar oscillator na RC na ciki da ke aiki a 8 MHz. Ana auna siginar analog daga amplifier mai jiwuwa ta mai jujjuyawar A/D kuma ana amfani da shi zuwa shigar da PC0. Shirin "yana zaɓar" daga siginar mai jiwuwa abubuwan da ke kwance a cikin mitoci masu zuwa:
- Maɗaukaki: 13… 14 kHz.
- Matsakaicin 6…7 kHz.
- Ƙananan 500 Hz… 2 kHz.
Sannan shirin yana ƙididdige ƙarfin haske ga kowane tashoshi kuma yana sarrafa transistor ɗin fitarwa daidai da sakamakon. Na'urori masu kunnawa sune transistor T1 ... T3 (BUZ11) tare da babban ƙarfin lodi na yanzu. Allon yana da shigarwar CINCH don shigar da siginar AUDIO kai tsaye tare da matakin 0,7 V (fitarwa na yau da kullun). Za a iya zaɓar tushen sauti ta amfani da SEL jumper: CINCH (RCA) ko makirufo (MIC).
An zaɓi tasirin tare da maɓallin MODE (S1):
- Launi ja.
- Launi shuɗi.
- Koren launi.
- Farin launi.
- Haske.
- Canjin launi bazuwar zuwa bugun bass.
- Banda.
Muna fara taron tare da masu siyar da siyar da sauran ƙananan abubuwa zuwa allon, sannan mu gama tare da haɗakar capacitors na lantarki, transistor, haɗin dunƙule da mai haɗin CINCH.
Ana iya siyar da makirufo kai tsaye zuwa madaidaicin tsiri tare da fitilun zinari. Na'urar da aka taru ba tare da kurakurai ba, ta amfani da tsarin microcontroller da abubuwan aiki, za ta yi aiki nan da nan bayan kunna wutar lantarki.
