Hi Jean Claude,I0_5 and I0_6 can work as a normal input, but you must configure the wiring and the switch configuration properly. Take a look that these pins have a not commune GND. Also you must have the switches PIN2/I0.5 and PIN3/I0.6 to ON position (M-Duino PLUS version).With that you should can use digitalRead(pin) like any other normal input pin.Best regards,
