• How to use the board ?

To obtain the value of the wanted resistor, you need to fill the boxes with your own values and the resistor and power boxes will fill up on their own !

• Supply voltage
  

This voltage is what feeds your entire circuit like a battery, a power supply,... you have to fill it with your own info, meaning which supply power voltage you want to feed your LED with. It has nothing to do with what you could find on the website !

• Operating voltage of the LED component
  

This value is on the product datasheet of every LED component.

• Operating intensity of the LED component
  

This value is on the product datasheet of every LED component

• Real resistor
  

This value gives you the ideal resistor value for your circuit. You just need to choose the closest superior resistor.

• Power

This value is necessary to choose the right resistor on the website. For instance, if the indicated value is 0.17 watt, it means you need a 1/4 watt resistor. You have to choose the closest value from what is recommended in the board.
