Nov yog lub voj voos uas LED ploj mus thiab OFF tsim qhov ua kom pom kev zoo heev.

Ntawm no, Kuv yuav qhia koj ob txoj hauv kev sib txawv los ua kom qhov kev sib tw ploj mus siv:

1. 555 Timer IC

2. Transistor

Kauj Ruam 1: Cov Cheeb Tsam Yuav Tsum Tau

Cov no yog Cov Cheeb Tsam Yuav Tsum Ua rau kev tsim hluav taws xob:

Kauj Ruam 2: Daim duab qhia chaw

Cov no yog Circuit Diagrams rau kev siv Circuit:

• 555 Sijhawm IC
• Transistor

Kauj Ruam 3: Qhia ib qib zuj zus

Cov vis dis aus no qhia ib qib zuj zus, yuav ua li cas thiaj tsim tau ob lub voj voog no.
