Controllino MINI/MAXI/MEGA sketch for Hintpad-I/O via serial com (USB) port

Setup

Using Controllino Input pins

As for now you can use all input pins as digital inputs only, i.e. if you want to use analog sensors you will need another microcontroller to process analog signals and report a HIGH signal to a Controllino input pin when the puzzle is solved OR if you want to use the pins as outputs, you will need to edit this sketch to your liking. But keep in mind that Hintpad does not support input pins as outputs!

Logic Voltage Levels

Logic switching levels depend on the supply voltage of the Controllino! Use the Pin-Header of non-"pure" Controllinos in order to use the native 5V logic.

Supply Voltage LOW HIGH
12V 0 - 3.6V 9 - 13.2V
24V 0 - 7.2V 18 - 26,4V
5V (pin header) 0 - 1.5V 3 - 5V
