RGB-hmo teeb, nrog lub peev xwm los tswj cov xim ntawm lub teeb pom kev tsaus ntuj siv tes txav. Siv peb lub ntsuas ntsuas nrug, peb yuav hloov qhov ci ntawm txhua ntawm peb yam ntawm RGB xim thaum mus txog lossis tshem tes. Lub Rooj Tswjhwm Saib Xyuas Arduino tau siv los ua microcontroller.
Kauj Ruam 1: Daim Ntawv Teev Npe
Txoj haujlwm xav tau cov ntsiab lus hauv qab no

Kauj Ruam 2: Hluav Taws Xob Hluav Taws Xob
Kauj Ruam 3: Lub Rooj Sib Tham Teeb
Kauj Ruam 4: Tsim Sketch
Kev txhim kho cov duab kos. Thaum tsim cov duab kos, kuv teeb tsa cov hauv qab no:
- qhov deb ntawm 1-20 cm, 1 - qhov siab tshaj plaws, 20 - xoom - qhov ntsuas qhov nrug nyob hauv lub voj nyeem cov ntaub ntawv thiab siv qhov kev ncua deb los teeb qhov ci ci - yog tias qhov kev hloov pauv ntawm 1-20 cm mus rau ntau dua 20 cm nyob rau hauv ib lub voj voog (tes mus rau sab) - qhov ci no tau kho rau cov xim no
Qhov ci ntsa iab tau teeb tsa los ntawm kev thov PWM teeb liab rau qhov tso tawm ntawm cov lej rau pawg R, G, B. qhov zaus ntawm PWM teeb liab yog kwv yees li 60 Hz. PWM teeb liab tau tsim raws li hauv qab no:
Piv txwv li, nrug deb li 5 cm
PWM teeb liab -15- (5-1) = 10 cuam tshuam kev cuam tshuam LEDs ntawm cov xim no tau zes 4-1-LEDs ntawm cov xim no tsis tau zes
