Then, we will declare a string field calledmessage, which will be also set to required. We will assign to it the unique number 2. required string message = 2; The final.protofile can be seen below. syntax = "proto2"; message StringMessage { required int32 integer = 1; required string...
/*Reading a serial ASCII-encoded string.This sketch demonstrates the Serial parseInt() function.It looks for an ASCII string of comma-separated values.It parses them into ints, and uses those to fade an RGB LED.Circuit: Common-Cathode RGB LED wired like so:- red anode: digital pin 3 th...

You can take advantage of some advanced C++ capabilities (streaming insertion syntax and templates) that you can use if you declare a streaming template in your sketch. This is most easily achieved by including the Streaming library developed by Mikal Hart. You can read more about this library ...
