Txawm li cas los xij, lawv xav tau ntau qhov kub hnyiab thiab ua haujlwm tsis zoo ntawm qhov kub thiab txias, tshwj xeeb tshaj yog thaum nyob ze rau lwm qhov muag.
Peb tsis tuaj yeem nrhiav cov ntaub ntawv tsis txaus ntseeg txog kev ua haujlwm ntawm cov hlau halide qhov muag teev ntawm qhov kub thiab txias. Thov hu rau peb yog tias koj muaj lus nug.
WINNER:
Lub Sijhawm Kub Kub
Yuav luag tsis muaj qhov sov so - lub sijhawm rau LEDs. Lawv qhov ci ntsa iab nce mus txog qhov siab tshaj plaws tam sim ntawd.
Nyob ntawm qhov ci ntsa iab, hlau halide teeb yuav tsum muaj qhov pom kev sov siab - lub sijhawm. Nws yuav siv sij hawm 15 mus rau 20 feeb rau hlau halide teeb nyob rau hauv cov kis las kis las kom ncav cuag lawv qhov kev ci ntsa iab.
WINNER: LED
lav
LEDs: Feem ntau 5-10 xyoo
Hlau Halide: feem ntau yog ib mus rau ob xyoos
WINNER: LED
