Choosing the Resistor to Use With LEDs
This question gets asked every day in Answers and the Forums: What resistor do I use with my LEDs? So I've put together several different ways to figure it out.Lets get right to it:Each of the steps do the same thing. Step 1 is the simplest and we go downhill from there. No mater what way you choose you must first know these three things:Supply voltage This is how much power you're putting into the circuit. Batteries and wall warts will have the output voltage printed on them somewhere. If y...
How an LED Works
Today I found out how an LED works. An LED or “Light Emitting Diode” is basically as the name describes; it is a special type of diode that is specifically optimized to give off light, usually in the visual or infrared spectrum, as electricity is passed through it. A diode is a special type of semiconductor that has many uses. One of [...]
we are going to explain how to connect led light to 220v ac
In this article we are going to explain how to connect led lights to 220 ac. In today life it become more interesting and more important because people wants short method and short circuits. So overcome to meet the challenge of modern age we show a simple method to bright led light to 220 volts AC. Led light shown in the following figure is so simple to make .
