programming using Arduino in C language, if you use libraries please provide where you get them.

A resistor is a circuit device designed to have a specific resistance value Retween its ends Resistance values are expressed in ohms or kilo-ohms Resistors are frequently marked with colored bands that encode their resistance values The first two bands are digits, and the third is a power-of-ten multiplier first band is green, the second is black, and the third is orange, the resistor has a value of 50101010 oHM or 50 koHM Write an Arduino program that prompts for the colors of Band 1 , Band 2 , and Band 3 , and then displays the resistance in kilo-ohms User can enter lowercase, uppercase, and / or mixed-case as inputs. The program is smart to process them correctly For example, flow of the program is, Enter the colors of the resistor's three bands, beginning with the band nearest the end Type the colors in lowercase, uppercase, and / or mixed-case letters Band 1 Green Band 2 black Band 3 YELLOW Resistance value: 500 kilo-ohms Enter the colors of the resistor's three bands, beginning with the band nearest the end Type the colors in lowercase, uppercase, and / or mixed-case letters
