AVT1853 - RGB LED
Chinokosha chepati yakabudirira haisi mimhanzi yakanaka chete, asiwo chiedza chakanaka. Iyo yakaratidzwa RGB LED mutyairi sisitimu inogutsa zvinotarisirwa zvevanonyanya kuda vanoenda kumapato.
Schematic diagram yeRGB illuminophony inoratidzwa muMufananidzo 1. Inosanganisira microcontroller, an operational amplifier uye simba transistors. Chiratidzo chekupinza kuburikidza ne capacitor C1 inodyiswa kune yekuisa yeanoshanda amplifier. Iyo yekuisa bias voltage inotarwa nedivider yakavakwa kubva kune resistors R9, R10, R13, R14. Iyo microcontroller (ATmega8) inovharwa neyemukati RC oscillator inomhanya pa8 MHz. Iyo analog siginecha kubva kuodhiyo amplifier inoyerwa neanalog-to-digital inoshandura uye inoshandiswa kune PC0 yekuisa. Iyo purogiramu "inosarudza" zvikamu kubva kuodhiyo siginecha inorara mune anotevera frequency renji:
- Pamusoro: 13…14 kHz.
- Avhareji 6…7 kHz.
- Yakaderera 500 Hz…2 kHz.
Iyo purogiramu inozoverengera kupenya kupenya kune yega yega chiteshi uye inodzora inobuda transistor zvinoenderana nemhedzisiro. Actuating midziyo inonzi transistors T1 ... T3 (BUZ11) ine yakakwirira ikozvino mutoro simba. Bhodhi rine CINCH yekupinda yekuisa yakananga yeAUDIO siginecha ine mwero we0,7 V (yakajairika headphone kubuda). Iyo yekuteerera sosi inogona kusarudzwa uchishandisa SEL jumper: CINCH (RCA) kana maikorofoni (MIC).
Mhedzisiro inosarudzwa neMODE bhatani (S1):
- Ruvara rutsvuku.
- Bhuruu ruvara.
- Green color.
- Ruvara chena.
- Mheni.
- Random color shanduko kune kurova kwebass.
- Kunze.
Isu tinotanga gungano nesolder resistors uye zvimwe zvidiki zvidiki kubhodhi, uye kupedzisa negungano re electrolytic capacitors, transistors, screw connections uye CINCH connector.
Maikorofoni inogona kutengeswa yakananga kune yakakomberedzwa tambo ine mapini egoridhe. Chishandiso chakaunganidzwa pasina zvikanganiso, uchishandisa yakarongwa microcontroller uye zvinhu zvekushanda, ichashanda nekukurumidza mushure mekuchinja magetsi ekupa.
