Arduino Led No Resistor at Riley Saltau blog

Arduino Led No Resistor. First, you will setup your circuit with an arduino board and an led, and then discover different ways to control the led. A typical approach is to connect an led + resistor (in series) to an io pin, and connect the other end to ground. A symbolic way, without an added resistor and for smaller currents, is \$i_{_\text{led}}\approx a\cdot\exp\left(b\cdot. You'll be both safe and in control by adding a small resistor in series (either with each individual led or, if the led pairs are balanced, with the whole led circuit). It's not adviseable at all to use leds without resistors (arduino digital i/o). In this complete tutorial you will learn how to use an led with arduino. In code, you make the pin an output, and bring it high and low repeatedly to flash the led. However, for multiplexed displays such currents are normal. The short answer is, yes and no, it depends on your arduino and it depends on the color of your led. Even a burnt cfl or led lamp can have some resistors that you could use. For instance, a 3.3v board does not. 330 ohm is just a minimum value, but as you want only an initial.
