I have load in arduino uno an example program to control RGB leds. Sending a string by usb leds switch on. I open arduino serial monitor tool and usb works: I send a string 255,127,35 and leds switch on to correct ligth intensity. Now I send the same string by Hyperterminal but leds don't switch on.
In arduino program the end of string is '\n'. In fact by serial monitor tool I set 'NL'. Can you help me?
What does Hyperterminal send at the end of the string ?
Maybe send a user input such as # at the end of the string and detect that in the Arduino code instead of '\n' or if Hyperterminal sends a Carriage Return detect '\r'
