Hluav Taws Xob/EM Ntes Ntes (yooj yim tshaj plaws): 3 Kauj Ruam

Nov yog qhov yooj yim tshaj plaws EM tshawb pom thaj chaw koj tuaj yeem pom hauv is taws nem. Kuv tsim nws tus kheej thiab nws tau piav qhia nws ua haujlwm li cas hauv cov kauj ruam tom ntej.

Yeej yog yam koj xav tau, yog ob lub transistors qee qhov tiv thaiv, kav hlau txais xov piv txwv ua los ntawm tooj liab hlau zoo li kuv, 3v npib roj teeb, PCB, LEDs thiab hloov.

Khoom siv

• NPN transistor BC547 x2
• 100 Ω resistor x2
• 3.3kΩ resistor
• Kav hlau txais xov (kuv yog los ntawm tooj liab hlau)
• 3v npib roj teeb
• Npib cov roj teeb tuav (kuv yog 3d luam tawm)
• PCB
• Hloov
• Txhua xim coj x2
• optionally npog

Kauj Ruam 1: Nws Ua Haujlwm Li Cas?

Cov cuab yeej no ntes tau EM qhov chaw uas tau tsim me me los ntawm cov khoom siv hluav taws xob lossis kab hluav taws xob hauv cov phab ntsa thiab hloov nws mus rau qhov hluav taws xob me me uas ua rau qhov hluav taws xob loj ntws los ntawm coj. Cov kauj uas koj tuaj yeem pom yog lub hauv paus kav hlau txais xov. Koj tuaj yeem siv nws los saib seb puas muaj hluav taws xob hauv qee yam, lossis nrhiav cov hlua hluav taws xob hauv phab ntsa.

Kauj Ruam 2: Txhuam Txhua Yam Ntawm PCB

Tau txais PCB thiab tsuas yog muab tshuaj txhuam rau ntawm nws hauv ib txoj hauv kev pom ntawm cov phiaj xwm. Kuv cov ntawv tau siv los ntawm 3 volt npib roj teeb tab sis koj li tuaj yeem siv tau los ntawm lwm yam, tsuas yog nco ntsoov hloov pauv tus tiv thaiv.

Kauj ruam 3: Ua tiav! Tsuas Xeem Nws

Nws yuav tsum ua haujlwm ib yam li hauv video. Thaum koj coj nws ze rau ntawm lub qhov hluav taws xob, LED yuav tsum ci. Koj tuaj yeem sim nrog lwm tus transistors, resistors thiab lwm yam LED ntsais muag nkaus xwb hauv cov vis dis aus, Kuv xav tias yog vim tias AC qhov hluav taws xob hauv qhov hluav taws xob, tso koj lub tswv yim hauv cov lus!
