Nqe lus piav qhia:

txoj haujlwm no ua raws los ntawm 3 lwm txoj haujlwm uas txhua tus nyob hauv tib pawg nrog ntau txoj hauv kev. peb tsuas yog sim ua/sim ua kab laum hmo ntuj hu nkauj uas yog ib qho ntawm cov suab nkauj ntxim nyiam tshaj plaws rau cov neeg feem coob. txhua qhov muab cov phiaj xwm hauv pab pawg no muab lub suab muaj txiaj ntsig zoo tshaj qhov ua tau nrog tsis lim dej tsis muaj suab nrov thiab siv ob peb yam pheej yig tshaj qhov muaj zog tshaj plaws. OK txaus khav theeb cia ua!

Sijhawm 555:

peb muaj 3 qhov sib txawv 555 ic siv hauv txoj haujlwm no uas txhua tus ntawm lawv nyob hauv Hom Astable. peb tsuas yog muab ob lub ic tso rau hauv ib qho kom lom zem dua yog li koj pom ib qho NE556 (uas yog ob NE555) thiab ib qho NE555. hla piav qhia lub sijhawm 555 vim tias muaj ntau txoj haujlwm muaj txiaj ntsig zoo/qhia rau ntawm nws muaj nrog saib hauv instructables.com. tab sis cia kuv muab qee qhov txuas muaj txiaj ntsig tsawg kawg:

555 Astable lub laij lej

www.instructables.com/id/555-Timer/

txhua yam peb ua yog ua raws Astable xam los muab cov zaus xav tau. ntawm qib 1 kuv tau tso cov duab uas yog qhov kwv yees kwv yees ua ntej ntawm qhov tshwm sim chirping uas qhia txog lub luag haujlwm thiab zaus siv tsuas yog hloov ob lub resistors thiab capacitor ib IC.

Khoom siv

IC

1. IC1 1 x NE555
2. IC2 1 x NE556

Resistors

1. R (2, 4, 5, 6, 7, 9) 6 x 10 KΩ
2. R (1, 3) 2 x 4.7 KΩ
3. R8 1 x 3.3 KΩ

Capacitors

1. C (1, 7) 2 x ceramic 4.7 nF
2. C (2, 3, 4) 3 x ceramic 10 nF
3. C5 1 x electrolytic 3.3 µF
4. C6 1 x electrolytic 47 µF

Transistors

1. Q1 1 x NPN 2n2222A
2. Q2 1 x PNP ss 9012

Lwm yam

BZ1 1 x Passive Buzzer (saib cov phiaj xwm kom hloov pauv tau)

Kauj ruam 1: Circuit Court

txhua yam meej. nws yog koj qhov kev xaiv siv 3x555 ic's lossis tsuas yog ib qho 556 + ib 555 rau qhov yooj yim.as koj pom ob lub cim thaj tsam ntawm cov phiaj xwm, peb siv Q1 los hloov IC1 cov zis. thiab lwm thaj av qhia hloov chaw sib txuas nrog cov uas twb muaj lawm passive buzzer module rau kev siv zog tsawg dua.

Kauj Ruam 2: Tsim

Kuv suav nrog pcb tsim rau koj. ntawm no kuj yog.pcb cov ntaub ntawv. siv mounted saib ua ntej (duab 2) rau solder jumpers kom raug. pcb loj yog 62mm x 77mm.
