Thov mus rau Raspberry Pi teeb tsa mus rau hauv kab lus ua tau zoo thiab txhawb koj li GPU nco kom txog thaum qhov yuam kev ploj mus (yuav tsum rov pib dua).

Tam sim no txhawm rau tsim cov duab uas yuav txuag rau lub desktop peb yuav siv cov cai hauv qab no:

los ntawm picamera ntshuam PiCamera #Imported module tsim los ntawm pip nruab pi lub koob yees duab hais kom ua los ntawm lub sijhawm ntshuam pw tsaug zog #Imported pw tsaug zog kom ntseeg tau tias peb lub koob yees duab nyob twj ywm

lub koob yees duab = PiCamera () #Setup rau lub koob yees duab

lub koob yees duab.start_preview () #Pib qhov pom ua ntej pw tsaug zog (5) #Lau qhov kev saib ua ntej rau 5 vib nas this

camera.capture ('/home/pi/Desktop/image.jpg')# Los ntawm

camera.stop_preview ()#Nres Qhov Saib Ua Ntej

Kauj Ruam 5: Tsim Circuit Court Nrog Code

Raws li pom saum toj no los ntawm daim duab qhia chaw peb yuav tsum teeb lub pob, LDR, thiab thaum kawg ob lub RGB LEDs. Ua ntej peb yuav teeb tsa lub pob ntawm sab laug sab laug ntawm lub khob cij. Thaum koj teeb tsa lub pob peb yuav siv cov kab tsheb ciav hlau sib txuas lub ntsiab lus uas peb yuav txuas rau peb 3.3V ntawm qhov zoo thiab hauv av rau qhov tsis zoo. Tom qab koj tau ua tiav kev teeb tsa Circuit rau khawm nkaus xwb.

Peb yuav sim peb qhov Circuit kom pom tias peb tuaj yeem ua tau li ntawd yog tias lub pob raug nias peb tig cov coj los siv cov cai hauv qab no:

#Imported Modules los ntawm gpiozero ntshuam khawm los ntawm picamera ntshuam PiCamera los ntawm lub sijhawm ntshuam pw

#Teeb tsa

Lub koob yees duab = PiCamera () Khawm = Khawm (22)

#Kev yees duab ua haujlwm, Kuv tau txiav txim siab muab nws tso rau hauv kev txhais ua haujlwm vim nws pab peb ntxuav cov cai tseem ceeb

def photocap (): cov

Camera.start_preview ()

pw tsaug zog (5) Camera.capture ('/home/pi/Desktop/image.jpg') print ("Photo was taken") Camera.stop_preview ()

#Main chaws:

thaum muaj tseeb: yog tias Button.is_pressed: print ("Nias lub khawm") photocap ()

#Vim li cas qhov no thiaj li ua haujlwm: Tus lej tseem ceeb ua haujlwm zoo li txhua yam peb tab tom ua yog siv cov lus txib yog tias khawm.is_pressed nyob rau lub sijhawm muaj tseeb nqe lus yog li nws tau hloov kho tas li thaum lub pob raug nias kom thaij duab

Tam sim no peb tab tom teeb tsa 2 RGB LEDs txhua txoj kev mus txog rau sab saum toj ntawm lub Circuit Court thiab cais lawv nyob nruab nrab ntawm lub khob cij thiab ua kom sib npaug. Yog tias koj tsis muaj 220 ohm resistors rau txoj haujlwm no koj tuaj yeem teeb tsa lawv ua ke nyob ntawm koj qhov kev tiv thaiv rau cov resistors koj muaj. Tus lej thib ob ntawm 4 tus pin RGB LED (qhov ntev tshaj yuav tsum txuas nrog hauv av hla txoj kev tsheb nqaj hlau. Lwm tus pin yuav tsum txhua tus txuas nrog lawv tus kheej GPIO pins. (Thawj tus pin = liab, Tus lej thib ob = hauv av, Tus Pin thib peb = ntsuab) Plaub, tus pin = xiav).

Peb yuav sim ib qho ntawm peb cov RGB LEDs hauv peb lub pob khawm nrog cov cai hauv qab no:

#Imported Modules los ntawm gpiozero ntshuam khawm los ntawm picamera ntshuam PiCamera

los ntawm gpiozero ntshuam RGBLED

los ntawm lub sijhawm ntshuam pw

#Teeb tsa

Lub koob yees duab = PiCamera () Khawm = Khawm (22)

TimedLED = RGBLED (liab = 21, ntsuab = 20, xiav = 16)

#Cov duab ua haujlwm nrog RGB LED, Kuv tau txiav txim siab muab nws tso rau hauv kev txhais ua haujlwm vim nws pab peb ntxuav cov cai tseem ceeb

def photocap (): Camera.start_preview () tsaug zog (4)

timedled.color (1, 0, 0)

tsaug zog (2)

timedled.color (0, 1, 0)

tsaug zog (1)

Camera.capture ('/home/pi/Desktop/image.jpg') print ("Photo was taken") Camera.stop_preview ()

#Main chaws:

thaum Muaj Tseeb:

yog Button.is_pressed:

print ("Nias lub khawm") photocap ()

#Vim li cas qhov no ua haujlwm: Qhov laj thawj vim li cas txoj cai no ua haujlwm yog vim tam sim no peb tau txais RGBLED los ua haujlwm raws li lub sijhawm rau thaum cov duab yuav raug coj mus.

Tam sim no teeb tsa Lub Teeb Dependent resistor nyob rau sab qis ntawm sab ntawm lub khob cij siv daim duab qhia txhua txoj hauv kev mus rau saum thiab cov kev tsheb ciav hlau sib tham ua ntej. Nco qab ob qho ntawm ob txhais ceg ntev ntawm LDR thiab tus kws tshaj lij yuav tsum txuas nrog GPIO tus pin.

Tom qab peb tau txuas nrog LDR peb yuav siv cov cai hauv qab no:

#Imported Cov Qauv
