What is the maximum number of LEDs I can fit on USB ?
What is the maximum number of LEDs I can hook upto to a USB port SAFELY ?
I have 3V LEDs (20mA I GUESS)and they come very cheap here around Rs.2 for 1 LED (25 for $1)
And how do I do that? Parallel would be the best I guess...,,I really don't know what current my PC can give safely...!
