This is hands-down the simplest LED resistor calculator you will ever find !

With this app you will be able to light up those LEDs in no time even when you know NOTHING about the subject.

You will even be able to calculate resistor values for LEDs connected in parallel !

What are you waiting for, time to light up those LEDs !

=========================================

The LED Resistor Value Calculator you had been looking for !
Choose your LED color and you will get the resistor value to use ! EASY!

You have an LED and a Battery; you just want to know the right resistor to use, not to read a chart or textbook to learn the 101 of electronics.

This is your answer.

We all love those bright blinky LEDs, and we all know we need resistors to make sure they don’t "Explode", ha ha ha

Unfortunately, every time we go to websites to find the answer, we are forced to fill in complicated stuff about the LED that if we know, we wouldn’t be asking...
Not anymore with this app :)

PS: Give the screen a left swipe to turn off all sounds and a right swipe to turn it back on.
