this question could be a bit too easy, but I didn't find a solution in the internet.
I'm looking for a simple ASCII decoder. If I have a a serial.read() function in my Arduino code, the value i receive is in ascii numbers. If i send a "a" to the Arduino, I'm receiving a "97". Or: If i send "arduino", i get the answer "97 114 100 117 105 110 111 "
Does anybody know a function to change these ascii-numbers back to letters and numbers.
Thanks and Greetings, Hendrik
