With the release of Arduino IDE v1.6.6, a new tool was given to the users called the Serial Plotter. The idea of it is to be able to visualize the data you return, beyond just seeing numbers spit out onto the serial monitor.

 

 

 

Most intriguing features are:

  • Long-awaited new arduino-builder: this is a pure command-line tool which takes care of mangling the code, resolving library dependencies and setting up the compilation units. It can also be used as a standalone program in a continuous-integration environment
  • Pluggable USB core: your Arduino can finally act as a lot of different USB devices without any need to change the core, thanks to the new modular architecture. Libraries based on the new subsystem are already being developed!
  • Serial plotter: you can now plot your data in realtime, as easy as writingSerial.println(analogRead(A0)) inside your loop

  • New goodies for library developers, like unlocked examples while developing and optional linkage into an archive
  • ArduinoISP example has been improved a lot and now you can flash your AVR chip using ANY other board (including third-party ones :) )
  • Both Libraries and Boards managers notify if a library/core can be updated with a simple popup – no more outdated code floating around!
  • A LOT of bug fixes, adjustments, documentation refinement thanks to our tireless users and contributors. The complete list of fixes and credits is available here.
