Finally, a CAPTCHA that separates the real engineers from the Stack Overflow copy-pasters! Good luck finding those 220Ω resistors without pulling out a multimeter and squinting so hard your eyeballs fall out.
Those blue ones? Maybe. The brownish ones with the red band? Could be. The tiny ones hidden behind that capacitor? Who knows!
I'd rather debug someone else's uncommented legacy code than prove I'm human with this electrical torture test. Somewhere, a hardware engineer is cackling maniacally.
