Yav dhau los peb tau siv PWM thev naus laus zis los tswj LED kom ci thiab tsaus. Hauv zaj lus qhia no, peb yuav siv nws los tswj lub RGB LED kom nyem ntau yam xim. Thaum sib txawv PWM qhov tseem ceeb tau teeb tsa rau R, G, thiab B pins ntawm LED, nws qhov ci yuav txawv. Thaum peb qhov sib txawv xim sib xyaw, peb tuaj yeem pom tias RGB LED ua rau pom cov xim sib txawv.

Kauj Ruam 1: Cheeb Tsam

- Arduino Uno board * 1

- USB cable * 1

- Tus tiv thaiv (220Ω) * 1

- RGB LED * 3

- Daim phiaj * 1

- Jumper xov hlau

Kauj Ruam 2: Txoj Cai

RGB LED txhais tau tias liab, xiav thiab ntsuab LEDs. RGB LED tau

tso cov xim sib txawv los ntawm kev sib xyaw 3 xim yooj yim liab, ntsuab thiab xiav. Yog li nws tiag tiag suav nrog 3 cais LEDs liab, ntsuab thiab xiav ntim rau hauv ib rooj plaub. Tias yog vim li cas nws muaj 4 tus coj, ib tus coj rau txhua ntawm 3 xim thiab ib qho cathode lossis anode nyob ntawm seb hom RGB LED. Hauv qhov kev qhia no kuv yuav siv cov cathode ib txwm.

Kauj Ruam 3: Daim Duab Schematic

Kauj ruam 4: Cov txheej txheem

Hauv qhov kev sim no, peb tseem yuav siv PWM uas, yog tias koj tau ua raws cov lus qhia txog tam sim no, koj twb muaj kev nkag siab yooj yim ntawm. Ntawm no peb tawm tswv yim tus nqi nruab nrab ntawm 0 thiab 255 rau peb tus pin ntawm RGB LED kom nws pom cov xim sib txawv. Tom qab txuas tus pin ntawm R, G, thiab B rau qhov txwv tam sim no, txuas lawv rau tus pin 9, tus pin 10, thiab tus pin 11 feem. Tus pin ntev tshaj (GND) ntawm LED txuas rau GND ntawm Uno. Thaum peb tus pin raug muab sib txawv PWM qhov tseem ceeb, RGB LED yuav tso tawm xim sib txawv.

Kauj ruam 1:

Tsim lub voj voog.

Kauj ruam 2:

Rub tawm cov cai los ntawm

Kauj ruam 3:

Tshaj tawm cov duab kos rau Arduino Uno board

Nyem rau Upload icon txhawm rau upload cov cai rau pawg tswj hwm.

Yog tias "Ua tiav uploading" tshwm nyob rau hauv qab ntawm lub qhov rais, nws txhais tau hais tias daim duab tau ua tiav tiav.

Ntawm no koj yuav tsum pom RGB LED nyem ncig liab, ntsuab, thiab xiav ua ntej, tom qab ntawd liab, txiv kab ntxwv, daj, ntsuab, xiav, indigo, thiab ntshav.

Kauj ruam 5: Code

// RGBLED

// Cov

RGB LED yuav tshwm liab, ntsuab, thiab xiav ua ntej, tom qab ntawd liab, txiv kab ntxwv, daj, ntsuab, xiav, indigo, thiab ntshav.
