Cov cuab yeej ua haujlwm nrog txhua qhov haujlwm lom zem thiab yooj yim ua, muaj ntau txhiab tus sensors thiab peb tau txais kev xaiv los xaiv lub ntsuas kom raug rau peb cov phiaj xwm lossis xav tau. Tab sis tsis muaj dab tsi zoo dua li tsim koj tus kheej lub ntsuas hluav taws xob DIY ua haujlwm nrog ntau yam ntawm cov tswj hwm me me yog li koj muaj cov qauv tsim uas koj xav tau rau koj txoj haujlwm.

Cov ntawv qhia no yuav yog ib feem ntawm Cov Ntawv Qhia uas kuv qhia koj yuav ua li cas txhawm rau tsim cov khoom siv sib xws nrog cov tswj hwm microcontroller tshaj plaws uas koj tuaj yeem pom. Hauv ob qho lus qhia dhau los, Kuv tau qhia koj yuav ua li cas thiaj li ua kom lub Tilt sensor, Kev co co thiab yuav ua li cas thiaj ua rau Touch sensor. Hauv cov lus qhia no, Kuv yuav qhia koj Yuav ua li cas tsim koj tus kheej lub teeb pom kev zoo, uas tuaj yeem siv ua ib hnub thiab hmo ntuj hloov lossis ua ib feem ntawm kev ruaj ntseg.

Kauj Ruam 1: Nqi Khoom

Nov yog cov npe ntawm yam koj yuav xav tau kom pib nrog kev qhia paub,

• LM358 IB
• LDR
• 10K Kaub
• LED
• 330 Ohm tus tiv thaiv
• 10K Resistor (Kuj)
• PCB (Tsis teb los tau)
• Txuas Txuas
• 5v Hwj chim Mov
• Cov qhob cij
• Soldering Hlau
• Soldering Hlau
• Soldering Flux
• Multimeter (Tsis teb los tau)

Kauj Ruam 2: Tshaj Tawm Circuit

Lub Circuit Court yog ua raws LM358 IC uas yog OP-AMP nrog kev khiav haujlwm ntau ntawm 3v txog 32v uas tsim nyog ua haujlwm nrog rau feem ntau micro-controllers ntawm logic qib 5V lossis 3.3V. LDR txuas nrog lub davhlau ya nyob twg tsis hloov pauv ntawm op-amp thiab txhua lub sijhawm pom lub teeb los ntawm Circuit Court nws ua rau muaj lub siab pule hla qhov tso tawm thiab LED tig ON.

Lub teeb liab tuaj yeem pub rau lub microcontroller ntawm tus Pin 1 ntawm LM358 IC.

Kauj Ruam 3: LDR

LDR yog cov khoom siv hluav taws xob uas nws qhov kev tiv thaiv hloov pauv raws li lub teeb pom kev tshwm sim ntawm nws. Thaum tsis muaj teeb pom kev zoo rau nws LDR muab qhov siab tshaj plaws tiv thaiv thiab thaum lub teeb pom kev tshwm sim ntawm nws qhov kev tiv thaiv qis dua, yog li ua kom muaj lub teeb liab hla lub dav hlau tsis hloov pauv ntawm Op-amp.

Kauj Ruam 4: Kev Ntsuas Siab Zoo

Qhov hloov pauv ntawm qhov hloov pauv ntawm qhov sib txawv ntawm 10K lub lauj kaub yog tias LED tseem nyob ntawm txawm tias thaum tsis pom lub teeb pom kev, koj yuav tsum hloov lub lauj kaub nrog tus ntsia hlau (yas ib qho pom zoo), kom txog thaum LED tua.

Kauj ruam 5: TADAAAA !! cov zis

Tom qab koj tau sim nws tawm ntawm lub khob cij koj tuaj yeem tsim nws ntawm PCB lossis raws li daim thaiv thaiv Arduino, rau lub caij nplooj ntoo hlav koj yuav tsum siv cov hlua ib leeg. Hauv cov lus qhia tom ntej, Kuv yuav qhia koj yuav ua li cas thiaj tsim lub siab ntsuas.
