How Much Voltage Does Led Need. A typical led needs 20ma of current. This led calculator will help you calculate the resistor values you will need when designing a series/parallel led array circuit. You basically fried the led because you did not limit the current to the led. Typically the 5mm red led uses about 2 volts with 20 ma max current, with the arduino output at 5 volts then you need to use about a 150 ohm resistor (brown/green/brown). This is a common question asked and is actually pretty easy to figure out. How much voltage do i need to light up an led? All you need to know is your led(s) forward voltage. If driving a led with a series resistor, you need a voltage that is above the forward voltage of the led at your desired operating current by a sufficient margin to account for led. The result, measured in watts, is the amount of power your leds use. To calculate an led's power use, simply multiply the led's voltage (in volts) by the led's current (in amperes).
