Hauv daim duab hauv qab no, koj tuaj yeem pom daim duab qhia chaw ntawm lub teeb ci LED yooj yim nrog ob lub npe NE555 ICs.
Kauj Ruam 1: LED Flasher Circuit Nrog Ob NE555 Chips
Ob qho 555s ua haujlwm raws li qhov tsis khov tsis khov, txhua tus muaj qhov sib txawv. Lawv cov txiaj ntsig tau txuas nrog hauv kev tawm tsam ob pawg ntawm LEDs. Qhov zaus thiab tus yam ntxwv ntawm lub teeb nyem tuaj yeem hloov kho los ntawm kev hloov pauv qhov tseem ceeb ntawm C2, C3, R2 thiab R3.
R3 thiab C3 cuam tshuam rau tus nqi nyem, R2 thiab C2 cuam tshuam rau xim hloov pauv tus nqi.
Koj kuj tseem tuaj yeem siv tus lej sib txawv thiab xim ntawm LEDs, tab sis koj yuav tsum tau kho tus nqi R1 kom tsis pub tshaj qhov siab tshaj tam sim no LED. Qhov tam sim no yuav tsum tsis pub tshaj qhov tso tawm tam sim no ntawm 555 Circuit, uas yog 200mA. Lub voj voog tuaj yeem siv tau los ntawm ib qho twg 12V (9-15V).
Hauv qab no yog cov npe khoom:
Chip NE555 - 2 pcs. Red LED - 4 pcs. Blue LED - 4 pcs. Capacitor 100 uF x 25V - 1 pc. Capacitor 1uF x 50V - 1 pc. Capacitor 100nF - 1 pc. 1MΩ resistor - 2 pcs. Resistor 270 Ohm - 1 pc. Roj teeb thaiv - 1 pc. Roj teeb 9V - 1 pc. Hlau rau tus ncej nrog txoj kab uas hla 0.8 hli thiab 0.5 hli
Hauv qab no yog cov duab ntawm qhov kev xaiv sib dhos flasher.
Kauj Ruam 2: Npaj Chaw Ua Haujlwm
Kauj Ruam 3: Sib dhos ntawm LEDs
Kauj ruam 4: Chip Harness
Kauj Ruam 5: Npaj Flasher Frame
Kauj Ruam 6: Peb Txhuam Txhua Yam Rau Tus Ncej
Kauj Ruam 7: Cov laug LEDs
Kauj Ruam 8: Daim Duab Tiav Tiav lawm
