Qhov no yuav yog lub zog uas sib xyaw lub nruas ncaws rau hauv lub suab tas. Nws yuav ua haujlwm zoo li koj xav tau yog tias nws yog 10K tus neeg tawm tsam, tab sis txhua yam tsawg dua 1M yuav tsum yog qhov zoo tag nrho.

Ib zaug ntxiv, Kuv tab tom txuas lub "siab" sab ntawm lub hwj chim mus rau txiv kab ntxwv, lub wiper kom daj, thiab sab "qis" rau ntsuab.

Cov "qis" xaim mus rau hauv av (tus tiv thaiv cov hlau lead hoop).

Cov wiper xaim mus rau 33K tus tiv thaiv uas txuas rau tus pin 13.

Cov kab "siab" mus rau ……. ua cas kuv tsis muaj daim duab no? Nws mus rau 10K resistor los ntawm kauj ruam 3 ntawm kauj ruam 20 LOL. Koj tuaj yeem pom 10K tus tiv thaiv uas kuv tab tom tham txog hauv daim duab thib peb, tsis muaj kev tsom mus rau hauv qhov xub ntiag. Tus tiv thaiv ntawd yog qhov chaw ncaws pob teeb liab yuav los rau hauv Circuit.

Nov yog lub ntsej muag uas kuv tau txheeb xyuas los ntawm tus qauv qub hauv kuv li kab ke. Tej zaum koj yuav siv qee yam me me me me thiab tsawg dua puag ncig. Tej zaum?

Daim npog ntsej muag no muaj qhov rau peb lub zog thiab peb lub jack, thiab LED (uas tseem muaj 1K tus tiv thaiv rau hauv av). Kuv xaiv los sau daim ntawv npog ntsej muag uas tsis txaus ntseeg nrog Sharpie zoo li hauv daim duab thib peb.

Thawj daim duab qhia pom xaim liab uas peb txuas rau "Kick In" jack. Nws txuas nrog 10K tus tiv thaiv uas "siab" sab ntawm qhov sib xyaw potentiometer txuas nrog. Tus resistor ntawd mus rau tus pin 2 ntawm TL074.

Daim duab thib ob qhia txog xaim dawb uas peb txuas rau lub "Suab Hauv" nkaus. Nws txuas nrog 47K tus tiv thaiv, thawj tus khub uas muaj LDR nyob nruab nrab.

Daim duab thib peb qhia txog xaim xaim txuas ncaj qha rau tus pin 1, uas yuav mus rau "Tawm" nkaus. Kuv tsis nco qab suav nrog nws hauv kuv qhov kev tsim, tab sis nws tsis yog lub tswv yim phem los suav nrog 220R resistor ntawm tus pin 1 thiab lub tso zis.

Nws yog qhov lom zem kom muaj LED los qhia koj ntau npaum li cas koj lub Circuit ua haujlwm! Qhov zoo ntawm tus thib ob LED tau txuas rau tus pin 8, qhov zoo ntawm LED uas twb tau suav nrog hauv peb lub Circuit Court. Muaj 1K tus tiv thaiv ntawm qhov tsis zoo ntawm lub LED twb tau nyob hauv lub ntsej muag uas txuas rau hauv av.

Daim duab thib ob ntawm qhov qhia pom tias muaj dab tsi tshwm sim.

Kuv siv cov xov hlau rub los ntawm Cat5 network cable. Ua haujlwm zoo heev.

Tau txais koj tus kheej qee qhov, txiav txim siab ua raws li kuv lub rooj sib tham xim, uas yog …

Txiv kab ntxwv = +12V, Xim av (lossis dawb) = 0V/av, Ntsuab = -12V

… Lossis ua koj tus kheej, tab sis nco ntsoov tias koj zoo siab heev nrog nws thiab tsis txhob hnov qab.

Cov +12V xaim mus rau tus pin 4 ntawm TL074. Cov -12V xaim mus rau tus pin 11 ntawm TL074. Nco ntsoov xyuas kom tseeb tias koj tsis txuas cov xov hluav taws xob rov qab. Hauv kuv qhov tsim ntawm no, nti yog qhov ntxeev, yog li nws yuav yooj yim los sib xyaw cov xov hluav taws xob. Cov chips no hlawv tawm tam sim thaum koj sim ua kom lawv rov qab los. Ib qhov xwm txheej kom zam!

Cov xaim av mus rau hauv av yooj yim. Hauv qhov kev tsim no, nws yuav txuas tus lej 12, qhov twg LDR txuas, tab sis koj tuaj yeem txuas nws txhua qhov chaw yooj yim.

Qhov kawg uas yuav tsum nco ntsoov (yam kuv tau hnov qab ntau zaus) yog ua rau koj lub vaj huam sib luag pem hauv ntej.

Thiab nrog qhov ntawd, peb ua tiav! Huag tos … koj tseem yuav tsum ua kom tsaus ntuj hauv koj lub cuab yeej LED/LDR. Cov kua nplaum yog zaum qhuav los txog tam sim no, yog li tau txais qee qhov xiav (lossis lwm yam tsis zoo) daim ntawv tshaj tawm cov xim thiab ua lub thawv me me rau koj lub tsev tsim Vactrol!

Txaus siab rau cov nyhuv goofy ducking! Nws tsim nyog nws!
