2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Lub tshuab hluav taws xob no tuaj yeem siv rau lub tswb nrov kom pom qhov tawg ntawm lub qhov rais iav los ntawm tus neeg nkag mus, txawm tias thaum tus neeg nkag mus ua kom ntseeg tau tias tsis muaj suab ntawm lub iav tawg.

Kauj Ruam 1: Nov Yog Qhov Project in Action

Kauj Ruam 2: Yuav Tsum Muaj Cov Npe

1x Pob Zeb Board

1 X Buzzer

1x Liab LED

1 x Potentiometer (1Mega Ohm)

1x Electrolytic Capacitor (10 uF)

1x Timer IC NE555

1x 3.3K ohm Kuj

2x 330k ohm Kuj

1x 1K ohm Kuj

1x 10k ohm Kuj

1 x BC548 Transistor

1x 100nF Ceramic Capacitor

1x 10nF Ceramic Capacitor

1 x Piezo Sensor

1 x 9V

1x Roj teeb Snap

Txuas xov hlau

Kauj Ruam 3: Tso Transistor rau ntawm Breadboard

Thawj kauj ruam koj yuav tsum tau ua yog tso lub transistor rau ntawm ib sab ntawm lub khob cij, koj yuav tsum tso nws rau ntawm ib sab kom muaj chaw txaus los ntxiv cov khoom seem uas tsis muaj teeb meem.

Kauj Ruam 4: Kev Sib Txuas Transistor

Muab cov resistors ntawm tus nqi raws li qhia hauv daim duab thiab ua qhov txuas. xaim dub yog xaim av.

Kauj Ruam 5: Piezo Sensor Kev Sib Txuas

Cov duab qhia hauv qib yog duab ntawm piezo buzzer. Hauv lub tsev qiv ntawv, lub piezo sensor tsis muaj yog li peb siv piezo buzzer hloov lub sensor.

Kauj Ruam 6: Kev Txuas Hluav Taws Xob

Cov kab rov tav ntawm lub rooj noj mov yog hu ua fais fab. Cov hlua hluav taws xob tsis txuas nrog hauv daim ntawv qhia zaub mov puv ntoob. Liab yog qhov zoo ntawm lub hwj chim thiab dub yog lub hauv paus ntawm lub hwj chim.

Kauj Ruam 7: Tso IC NE555

Tom ntej no, koj yuav tsum tau ua yog tso IC NE555 nyob rau lwm sab ntawm daim ntawv tais, koj yuav tsum muab nws tso rau ntawm lwm sab yog li muaj qhov chaw txaus los ntxiv cov hlau thiab cov khoom tsis muaj teeb meem.

Kauj Ruam 8: Transistor thiab NE555 Kev Sib Txuas

Txuas tus neeg sau ntawm transistor mus rau tus lej nkag (Pin2) ntawm IC NE555 los ntawm cov khoom siv hluav taws xob ntawm tus nqi 100nF. Cov kev sib txuas tag nrho tau qhia hauv cov duab.

Kauj Ruam 9: IC NE555 Kev Sib Txuas Fais Fab

Txuas tus pin1 ntawm IC rau hauv av thiab tus pin4 & pin8 rau txoj kev tsheb nqaj hlau zoo ntawm lub zog siv.

Kauj Ruam 10: LED Txuas

Txuas lub LED mus rau tus pin tso tawm (tus pin3) ntawm IC los ntawm cov kab tawm tsam. Series resistor yog rau limiting tus nqi ntawm tam sim no. Dub yog av xaim.

Kauj Ruam 11: Kev Sib Txuas Buzzer

Txuas lub buzzer rau tus pin tso tawm (tus pin 3) ntawm IC. Lub tswb nrov kuj tseem yog cov tiv thaiv sab qaum teb kom txuas cov xov hlau zoo mus rau IC thiab tsis zoo rau hauv av.

Kauj Ruam 12: IC Pin 6 & 7 Kev Sib Txuas

Luv tus Pin 6 thiab 7.

Kauj Ruam 13: Kev Txuas Hluav Taws Xob Hluav Taws Xob

Nco tseg- Cov hluav taws xob hluav taws xob yog cov khoom siv sab qaum teb yog li xyuas ob qhov kev sib txuas txhua lub sijhawm koj txuas cov khoom siv sab qaum.

Sab nyiaj ntawm lub capacitor yog sab tsis zoo thiab lwm qhov yog sab zoo.

Txuas lub davhlau ya nyob twg zoo ntawm tus capacitor rau tus pin 6 ntawm IC thiab tsis zoo rau hauv av.

Kauj Ruam 14: Kev Txuas Hluav Taws Xob

Txuas lub potentiometer tib yam li tau qhia hauv daim duab tsis yog, nws yuav nyuaj rau koj kom txuas.

Txuas ib lub davhlau ya nyob twg rau tus pin6 ntawm IC thiab so ob qho kom zoo ntawm lub zog fais fab.

Kauj Ruam 15: Pin 5 Kev Sib Txuas

Txuas tus pin 5 mus rau cov khoom siv hluav taws xob ntawm tus nqi 10nF thiab tsaws lwm tus pin ntawm lub capacitor.

Kauj Ruam 16: Kev Sib Txuas Hluav Taws Xob

Txuas ob sab ntawm txoj hlua fais fab. Cov dub yog cov tsheb ciav hlau hauv av thiab liab yog txoj kev tsheb ciav hlau zoo.

Tom qab ntawd txuas lub roj teeb rau hauv Circuit Court.
