I am currently busy with a project that requires me to use an Arduino and 3 potentiometers (to change background in RGB format) to write values through the serial port and read and separate them in processing.
What I want to do is to be able to use my Arduino to write multiple values to a processing program. I am quite new to coding and its been a while since I worked with my Arduino. I know how to read and write one value, but not multiple values.
Also is there a way to write 20 values?
Thanks in advance!
