Hello,

Are the inputs from the Arduino held high by the internal pullups or do we need to use external pullup resistors.

If anyone knows the answer, pls reply.

Thanks,

Koos

Hi

For a detailed and correct reply Stephan will awnser.... he is our electrical guy.

But in short words.... Nu Pull Up resistor is needed.

For a Input you simply wire : Pin to Switch - Switch to Ground.
Good Luck !

Hi Koos,

welcome to MobiFlight!

Pizman is right. The internal pullups are activated by the MobiFlight- firmware.

Stephan
