How Do You Design A Simple LED Circuit?
LED circuits are very easy to design. An LED or Light Emitting Diode, is a very low current light source that is very safe and durable for use in your project. This article will show you how to design and build a very simple LED circuit. The first step is to choose how many LED’s you want to light and their type (color, brightness). With this simple circuit you will be somewhat limited by the amount of voltage that can be safely provided for your project. Calculate the amount of voltage you need from your power supply. Look for the “diode forward voltage” specification from the manufacture’s website or packaging. If you do not have this information you can use the following to estimate: Red or Orange 2.0 V Yellow 2.1 V Green 2.2 V True Green, Blue, White 3.3 V Blue (430 nm) 4.6 V Say you want to have 3 Red LED’s in your circuit. Only use the diode forward voltage value. So, 3 x 2.0 = 6V, needed. Once you have the required voltage, choose how you want to power the circuit. Do you want t
