See element on mõeldud ainult Trellis draiveri PCB koostu jaoks: LED-id ja nupud ei ole kaasas. Trellis on avatud lähtekoodiga taustvalgustusega klahvistiku draiverisüsteem. Seda on lihtne kasutada, see töötab mis tahes 3 mm LED-iga ja ühisel I2C siinil saab kokku plaatida kaheksa plaati.

See PCB on spetsiaalselt valmistatud sobima Adafruit 4x4 elastomeerist klahvistikuga. Igal Trellis PCB-l on 4x4 padjakesed ja 4x4 sobivad kohad 3mm LED-ide jaoks. Pardal olev vooluring käsitleb 4x4 paani taustaklahvide vajutamist ja LED-valgustust. Sellel pole aga mikrokontrollerit ega muid "ajusid" – Trellise juhtimiseks on vaja Arduinot (või sarnast mikrokontrollerit), et lugeda klahvivajutuse andmeid ja anda teada, millal LED-id vastavalt soovile süttida.

Igal plaadil on juba I2C juhitav LED-sekvenser ja klahvistiku lugeja. Kiip suudab juhtida kõiki 16 LED-i eraldi, lülitades need sisse või välja. See ei saa halltoone ega hämardamist. Sama kiip loeb ka kõik kummiklahvistikuga tehtud klahvivajutused. Ühendused on "dioodmultipleksitud", nii et te ei pea muretsema mitme klahvi vajutamisel "kummituse" pärast, iga võti on adresseeritud ainulaadselt.



Iga LED on multipleksitud püsivoolu draiveriga, nii et saate segada ja sobitada mis tahes värve, mis teile meeldivad. Teil pole vaja, et see oleks üleni sinine, punane jne. Segage seda! Kasutada võib mis tahes 3 mm LED-i, kuigi leiame, et kõige paremini näevad välja hajutatud LED-id, mille heledus on 250 mcd+.

See element on mõeldud ainult Trellis draiveri PCB koostu jaoks: LED-id ja nupud ei ole kaasas. Tõenäoliselt soovitevalida sobiva nupupadjaja ka3 mm hajutatud LED -id(soovitame punast, sinist või valget, mis näevad kõige paremini välja). Valgusdioodide PCB-sse panemiseks ja seejärel igast trellist Arduino mikrokontrolleri (või mis tahes teie eelistatud mikrokontrolleri) juhtmete kinnitamiseks on vaja jootmist.

  • Mõõdud: 60mm x 60mm x 4mm
  • See plaat/kiip kasutab I2C 7-bitiseid aadresse vahemikus 0x70-0x77.
