I'm gathering data from 6 different sensors. I would like to combine that data into one string that I can send over bluetooth to my mobile phone. The string I want to make will look something like: "123|456|321|25.3|432|e", so I want to separate the values by |-signs. In Processing for example I would do this: String my_string = ""; my_string = 123 + "|"; my_string += 456 + "|"; etc. Or something to that effect. How do you build a string like that with Arduino? Thanks for any help, best, danielle.
