Sveiki,
užsiimsiu šiokia tokia saviveikla - darbščiųjų rankų burelis.
Gaminsiu LED lemputę and 12v. LEDukų prisisiunčiau. Mintis aiški kaip ką 
lituotis ir dėliotis.
Internetinis įrankis nubraizo tokią schema:
Solution 0: 3 x 7 array uses 21 LEDs exactly

      +12V       R = 100 ohms
                R = 100 ohms
                R = 100 ohms
                R = 100 ohms
                R = 100 ohms
                R = 100 ohms
                R = 100 ohms


the wizard thinks 1/4W resistors are fine for your application

va čia ir sustoju su rezistoriais. kokio reik? cia modelių pasirinkimas 
belenkoks 
http://www.prekespigiau.lt/rezistoriai/371-tiksls-rezistoriai-1-025w.html 
turbut reik 100R?  o jie veiks normaliai su 12V sistema, nes aprašyme "Max. 
Working Voltage: 250V"?
Nemuškit stipriai, senokai mokyklą baigiau :) nepamenu visų desnių ir 
skaičiavimų.

Kuo skiraisi 100R nuo 100K?

Dėkui už komentarus.
DJ
