Peb ib txwm siv qhov ua haujlwm txuas mus ntxiv ntawm lub ntsuas cua kom paub qhov txuas ntxiv hauv PCB, xov hlau, cov kab hauv qab, ntsuas qhov ua txhaum, thiab lwm yam. Thaum txuas ntxiv pom lub Buzzer sab hauv lub ntsuas 'meter' thiab thaum tsis muaj txuas ntxiv nws tsis nrov.

Peb yuav nyob ntawm no ua qhov zoo ib yam los ntawm kev siv tsuas yog Tus Kheej Sib Piv thiab qee qhov tiv thaiv.

Qhov no yuav pab peb ua kom muaj kev sib tw ntawm peb tus kheej thiab tseem yuav muab peb piv txwv piv txwv ntawm kev ua haujlwm ntawm OPAMP ua piv txwv,

Kauj Ruam 1: Qhov Yuav Tsum Tau

1. LM358 IC

2. 3 1K resistor

3.10K lauj kaub

4. LED

5. Buzzer

6. Cov xov hlau

7. Txiv neej headers

8. Cov khoom siv Perfboard thiab Soldering

Kauj ruam 2: Txoj kev xav

Peb tsuas yog siv OPAMP ua piv txwv los txhim kho qhov no..

Pom tias 10K lub lauj kaub tau siv los teeb tsa qhov ntsuas hluav taws xob ntawm 3V thiab pub rau hauv Tus Tsis Hloov pauv tus lej ntawm OPAMP … peb qhia qhov no 3V li V+…

lub resistor faib nrog 3 1K resistor tau siv. Cia qhov hluav taws xob ntawm kev hloov pauv tswv yim yog V_. Tam sim no thaum muaj qhov txuas ntxiv qhov hluav taws xob ntawm kev hloov pauv tus lej ntawm OPAMP yuav mus rau 2.5V (vim tias tam sim no 1K nruab nrab yog luv thiab qhov hluav taws xob nyob nruab nrab ntawm kev faib tawm tam sim no 5*1/(1+1) = 2.5V)…. Thaum tsis muaj qhov txuas ntxiv, nws yuav yog 3.33V (5*(2/3) = 3.33)….

Yog li thaum muaj qhov txuas ntxiv V_V+ thiab yog li tso tawm yog LOW thiab LED lossis Buzzer tsis nrov.

LM358 tau siv ntawm no thiab kev sib faib resistor nrog 1K tus nqi raug siv, hauv kev tshawb fawb ib qho 3 resistor ntawm tib tus nqi yuav ua rau tib qhov txiaj ntsig.

Kauj Ruam 3: Kuaj Lub Circuit Court ntawm Breadboard

sib sau ua ke koj cov khoom sib xyaw thiab txhim tsa hauv daim ntawv qhia zaub mov … daim duab qhia chaw yog hauv cov kauj ruam dhau los … qhov no yog rau kev ntsuas lub hom phiaj … tshem tawm ob lub xov hlau raws li kev soj ntsuam txuas mus ntxiv

tom qab tsim kho muab 5V cov khoom siv thiab luv cov xov hlau.. LED yuav tsum ci tam sim no, txwv tsis pub nws yuav tsum tawm.

Tam sim no koj tuaj yeem ua nws hauv Veroboard

Kauj ruam 4: Soldering

Tam sim no kom siv nws, koj yuav tsum tau muab nws tso rau ntawm ib qho ntawm Perfboard..see kuv tus qauv ntawm Circuit hauv Pics … khaws daim duab qhia chaw ib sab ntawm koj thaum siv lub tshuab … txuas lub roj teeb davhlau ya nyob twg rau nws

Tam sim no sim nws dua … yog tias tsis ua haujlwm zoo li ua ntej …. sim ua tib zoo saib cov kab hauv qab hauv lub teeb thiab tsom iav …

Tam sim no koj tau teeb tsa thiab npaj txhij mus nrog koj qhov kev ntsuas txuas ntxiv mus..

(Nco ntsoov tias kuv tsis tau siv kuv Buzzer hauv PCB vim kuv tsis muaj ib qho ntxiv … Koj tuaj yeem siv nws ib yam nkaus nrog rau LED)
