Arduino Why Do I Need A Resistor. as the name suggests, resistors resist the flow of electricity and the higher the value of the resistor, the more it resists and the less electrical. This does invert your logic so that a pressed button reads low and a not. This is lethic from marginally clever. The led by itself will. the answer from stevenvh explains what you need to do, but you also must calculate the power dissipation. the resistor to 5v is internal to the chip. you need to size the resistor to limit the current to what the arduino is capable of providing. a resistor drops a certain voltage across it when a specific current flows through it (read up on ohm's law.). They are really useful when trying to prevent sensitive electronics from breaking. use resistor with arduino led project: resistor restrict the flow of electricity. If you need to drop a. the resistors are to keep the led's from drawing too much current. If an led is rated for 30ma and it is supplied 5v. This tutorial will show you how to use resistors in your arduino led project.
