Cov lus qhia no yuav qhia koj yuav ua li cas txhawm rau ntsuas lub suab me me los ntawm cov khoom pheej yig koj tuaj yeem tau txais ntawm Radioshack. Nrog txoj haujlwm zoo no, koj tuaj yeem hloov qhov ci ntawm lub ntsuas. Nov yog kuv thawj qhov kev qhia, yog li thov nco ntsoov qhov yooj yim ntawm cov kauj ruam. Txaus siab rau !!
Kauj ruam 1: Cov ntaub ntawv
Txog qhov kev qhia no, koj tuaj yeem tshem tawm cov khoom hauv tsev thiab/lossis mus rau Radioshack thiab khaws lawv.
Qhov chaw: - 1 LED - Cov Caj Npab Qaum - Teeb ntawm Infrared Emitter thiab Ntes (Radioshack #276-0142) - 1 Cov Ntawv Me/Cov Ntaub Ntawv (Hais txog 3.5 "x2.5" x1 ") - 2 3V Npib Cells - 1 PNP Transistor
Kauj ruam 2: Emitter
Muaj ob ntu rau qhov kev qhia no- tus tso tawm thiab lub ntsuas. Tus emitter yog yooj yim heev.
Lob qhov tsaus nti LED los ntawm cov duab infrared- qhov no yog tus tso tawm. Pinch ob txoj hlua ua ke, tab sis nco ntsoov tias lawv tsis kov. Qhov no yuav cia cov npib cell haum khov kho. Xaub lub npib cell nruab nrab ntawm ob txoj hlua. Ntev ntev yuav tsum tau kov qhov zoo ntawm lub roj teeb, thiab sab luv yuav tsum kov sab tsis zoo. Koj tuaj yeem ua txhua yam no tom qab kom txuag lub roj teeb.
Kauj ruam 3: Ntes
Ntu no yog lub tshuab ntsuas hluav taws xob. Nws yog me ntsis nyuab dua. Koj tuaj yeem siv daim ntawv qhia zaub mov lossis tsuas yog ua haujlwm ntawm lub nkoj.
Tam sim no coj lub teeb pom tseeb LED tawm ntawm cov duab infrared- qhov no yog lub ntsuas (tseem hu ua phototransistor). Txuas lub davhlau ya nyob twg tsis zoo ntawm 3V Roj teeb rau qhov tsis zoo LED prong siv tus nab kuab. Txhawm rau ua qhov clip nyob ntawm lub roj teeb, Kuv tau siv Neodymium hlau nplaum, tab sis koj tuaj yeem xev nws xwb. Txuas qhov zoo coj mus rau tus xa tawm ntawm PNP transistor. Txuas tus neeg sau ntawm transistor mus rau sab zoo ntawm lub roj teeb. Txuas lub hauv paus ntawm lub transistor mus rau qhov ntsuas tsis zoo. Tom qab ntawd txuas cov xaim los ntawm tus xa tawm ntawm PNP transistor mus rau qhov ua tau zoo ntawm lub ntsuas. Tam sim no, ua tib zoo, muab tag nrho cov kab hluav taws xob tso rau hauv lub thawv me me, tawm hauv lub tshuab kuaj pom yooj yim.
Kauj ruam 4: Siv Nws
Txhawm rau siv koj lub tshuab ntsuas lub tsev, txheeb xyuas txhua qhov kev sib txuas, tom qab ntawd ua raws cov theem no:
Ua ntej tshaj, koj teeb tsa ob lub vojvoog kom tus emitter ncaj qha hla ntawm lub ntsuas. Tawm ntawm ib nti nrug nruab nrab ntawm lawv. Los so koj txhais tes los ntawm qhov sib txawv. LED yuav ntsais muag !! Tam sim no, txav tus emitter rov qab me ntsis ntxiv, thiab los so koj txhais tes dua. Ua qhov no kom txog thaum koj tuaj yeem tau txais qhov sib txawv loj heev. Txaus siab rau!
Kauj Ruam 5: Daim duab Circuit Court
Daim duab kab hluav taws xob no tuaj yeem pab koj nkag siab txog kev sib txuas.

Arduino Tsheb Rov Qab Chaw Nres Tsheb Ceeb Toom | Cov kauj ruam ib kauj ruam: Hauv txoj haujlwm no, kuv yuav tsim qhov yooj yim Arduino Tsheb Rov Qab Tsheb Nres Tsheb Nres Sensor Siv Arduino UNO thiab HC-SR04 Ultrasonic Sensor. Qhov no Arduino raws Lub Tsheb Rov Qab ceeb toom tuaj yeem siv rau Kev Tshawb Fawb Txog Tus Kheej, Robot Ranging thiab lwm yam
Motion Detector Siv NodeMCU: 5 Kauj Ruam
Motion Detector Siv NodeMCU: Hauv txoj haujlwm no, los ntawm kev siv lub suab txav txav koj tuaj yeem kuaj pom tias muaj tib neeg lossis tsiaj txhu nyob. Thiab los ntawm lub platform hu ua thingsio koj tuaj yeem saib xyuas hnub thiab sijhawm uas qhov pom muaj tshwm sim
Motion Detector Siv Thingsai.io Iot Cloud Platform: 6 Kauj Ruam

Motion Detector Activated Vanity Light: 6 Kauj Ruam
Motion Detector Activated Vanity Light: Kuv tau yuav lub tshuab ntsuas hluav taws xob infrared ntawm lub eBay rau $ 1.50 thiab txiav txim siab muab nws tso rau hauv kev siv tau zoo. Kuv tuaj yeem tau ua kuv tus kheej lub ntsuas ntsuas lub rooj tsavxwm, tab sis ntawm $ 1.50 (uas suav nrog 2 lub lauj kaub tais rau kev kho qhov rhiab heev thiab kaw lub sijhawm) nws yuav tsis
