Some LED circuits explained examples from various projects: flashing LEDs, 220V LEDs and more.
Above two types were the normally LED circuit products.
But to LED circuits builders or LED circuit board designer must know more electronic knowledge.
You must make some calculations to figure out the resistor value, depending on voltage power supply, LED voltage drop and desired current.
