Peb txhua tus paub tias 555 yog ib qho kev hloov pauv ntawm ib qho kev sib txuas uas nquag siv hu ua multi-vibrator. Ne555 lub sijhawm teev sijhawm yog siv rau lub sijhawm ua haujlwm yooj yim los ntawm qhov uas peb tuaj yeem tsim lub suab (suab) ntawm qhov tshwj xeeb. Ntawm no, peb tab tom tsim kev tsim hluav taws xob siv ne555 tus timer nti. Lub sijhawm ne555 tau ua haujlwm nyob rau hauv hom astable yog li thaum hloov pauv raug nias, tus hais lus ua suab nrov nrov. Yog tias tso tawm nws lub suab qis dua thiab 30 s tom qab tso tawm qhov hloov pauv lub suab tau raug tua.

6V roj teeb clip

nqe 55 5

8 ohm hais lus

khawm

wb 547, bc557

capacitors: 100u, 10n (2)

resistors: 220k, 100k, 33k, 22k, 1k, 39, 5.6 ohm

Koj tuaj yeem pom lub voj voog hauv daim duab hauv lwm qhov los qhia kom ntxaws.

Peb paub tias lub sijhawm ne555 muaj 8 tus pin. Peb tsaws tus pin 1. Ib qho kawg ntawm 10nF capacitor yog hauv av thiab tom qab ntawd txuas tus pin 2 thiab 6 nrog 33k ohm resistor nyob rau hauv parallel. Ib qhov kawg ntawm 10 nF capacitor yog tsaws qhov twg raws li qhov kawg dhau los ntawm 33k ohm resistor tau txuas nrog tus pin 3 thiab 1k resistor hauv kev sib txuas.

Lwm qhov kawg ntawm tus tiv thaiv yog tom qab txuas nrog lub hauv paus ntawm bc547 transistor hauv koob. Tus emitter ntawm lub transistor yog tom qab hauv av thiab tom qab ntawd tus neeg sau khoom txuas nrog tus hais lus rau 39 ohm resistor rau 6V lub hwj chim muab tag nrho hauv koob.

Tom qab ntawd koj yuav tsum tau tsaws ib qho kawg ntawm 10nF capacitor thiab lwm qhov kawg rau tus pin 5.

Hauv av ib qho kawg ntawm 100 uF lub tshuab hluav taws xob thiab txuas txuas thiab 22k ohm resistor nyob rau hauv parallel rau lub capacitor. Txuas 100k ohm resistor hauv koob nrog 100 uF capacitor uas tom qab ntawd yuav txuas nrog 220k ohm resistor thiab teh puag ntawm bc557 transistor.

Tus neeg khaws khoom tau los rau 6V lub zog siv hluav taws xob ntawm bc557 transistor thiab tus xa tawm tau txuas nrog tus pin 8 thiab 4 ntawm n555 timer.

Kauj Ruam 2: Nws Ua Haujlwm Li Cas?

1) Peb txuas lub roj teeb 6V.

2) peb nias qhov hloov pauv li 5 vib nas this.

- Soj ntsuam lub suab quaj nrog nce suab.

3) Lub capacitor C1 pib them.

4) Thaum them mus txog 2/3 ntawm Vcc, lub tshuab hluav taws xob pib tso tawm thiab thaum tso tawm yog tias nws nce mus txog 1/3 ntawm Vcc tom qab ntawd rov ua lub tshuab hluav taws xob pib them nqi uas tom qab ntawd ua rau cov mem tes.

5) Transistor yog hauv av tsuas yog thaum nws pib ua raws li nws tau txuas nrog rau cov zis yog li ntawd tus neeg hais lus tsim lub suab quaj.

6) Thaum koj tso qhov hloov pauv, lub suab yuav nres nrog lub suab qis nrog lub sijhawm. Nws ntev tshaj 30 s kom txog thaum lub suab raug kaw tag.

Kauj Ruam 3: Cov ntawv thov:

Raws li peb paub tias lub suab tsis hloov tam sim ntawd yog li muaj kev txwv siv tab sis muaj npe nrov nyob qhov twg kev ruaj ntseg tau teeb tsa. Yuav siv tau nyob rau lub sijhawm tawg, tub sab, lossis kev puas tsuaj los ceeb toom.
