Visuino PRO offers the users to use their own C code, or use the existing one from the Arduino to create a custom component. This is very useful when you you want to use a certain library from Arduino but is not supported yet in Visuino or if you created your own code in Arduino and would like to use it with Visuino.
In this Tutorial you will learn about Custom Code – OnInit, OnStart, and Direct Pin Manipulation
