Kawm Yuav Ua Li Cas DIY Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob uas tuaj yeem tsim cov tsheb tub ceev xwm lub suab nrov, lub tsheb thauj neeg mob thaum muaj xwm ceev & hluav taws kub lub suab siv IC UM3561a Siren Tone Generator.

Lub Circuit Court tsuas xav tau ob peb yam thiab tuaj yeem muab tso ua ke ob peb teev. Txij li lub siren yog ntau lub hom phiaj, nws tuaj yeem tsim kho kom yooj yim kom haum rau nws lub tsheb lub tsaj xav tau.

Kauj ruam 2: UM3561 piav qhia

UM3561 yog tus nqi qis, lub zog qis CMOS LSI tsim los siv rau hauv cov khoom ua si. Txij li kev sib xyaw ua ke suav nrog oscillating thiab xaiv cov kab hluav taws xob, lub suab sib cog lus tuaj yeem tsim nrog tsuas yog ob peb yam ntxiv. UM3561 muaj lub program npog ntsej muag ROM kom siv tshuab hluav taws xob rov ua suab nrov.

Kauj Ruam 3: Circuit Schematic

Tsuas yog ib qho ntawm Siren suab paj nruag tuaj yeem ua si ib zaug. Qhov no tau txiav txim siab los ntawm txoj haujlwm ntawm SP3T Slide switch. Qhov hloov pauv muaj peb txoj haujlwm uas yuav txuas rau lub davhlau ya nyob twg nrog VCC, GND lossis NC txhawm rau ua kom tiav Cov Lus Tseeb.

220KΩ resistor yog siv los teeb tsa qhov oscillating zaus ntawm IC.

Tus hais lus zoo tau tsav nrog sab nraud NPN transistor. Ib qho SPDT hloov tau siv los tig lub Circuit Court ON & OFF.

Kuv tsim lub rooj tsavxwm uas siv Txoj Kev Hlau.

Kuv drilled plaub qhov sib dhos hauv txhua lub ces kaum nrog txoj kab uas hla ntawm 3mm.

PCB loj yog 3.3cm X 3.3cm.

Kauj Ruam 5: Circuit Court Assembly

Muab thiab ua kom tag nrho cov khoom siv rau PCB. Muab ob npaug rau xyuas cov khoom nrog polarities. Thaum kawg, muab lub Hwj chim adapter thiab tus hais lus rau PCB.
