Introduction: Converting Integer to Character Arduino
Converting an integer to character is an easy process. It involves first changing the integer into a string and then converting the string into a character array. The reason i am posting this short post is because just recently i realized that many people do not know how to convert an integer to a character, me included (well, but now i know).
I going to start with the easier option - Converting a character to integer, then move on to our point of interest.
Step 1: Character to Integer
To convert a character to an integer you use this short statement:
Step 2: Integer to Character
This is more intricate than the last one. However, it is not as difficult as some (including me before I learnt how to do it) might think.
Here is the code:
By running this code, you will be able to convert an integer, into a character. However, as you will notice, the code above can only do conversions of numbers between -9 to 99 (thanks to a buddy who noted that on the comments). To be able to convert larger integers, change the array size of the character. Therefore, instead of:
you can use
to accomodate a n integer that has 5 digits. You can use any other array size depending on the size ofthe integer you want to convert.
