Hi all,

I have run the PB tutorial and have the problem that the output is the opposite of the parking brake state. I.e.

PB ON = LED OFF;
PB OFF = LED ON

The LED is also ON at all other times when the Arduino is powered.

Did anyone else encounter this and have a solution?

Thanks

Thats Not Correct.

There must be a Issue in your Wire work OR In Your config OR in your Workaround of Using the MF-Arduino System at all.
NOW the other Problem with your relais from different topic also makes sense... We have a "Problem" , Houston !

For Testing:
1. Confirm your LED is NOT at Pin 0 or Pin 1

2. Please Confirm problem is still there after a complete RESTART.
Dissconnect Arduino from USB .... Close MF Software ..... Wait 10 Sec .... Reconncet Arduino .... Start MF............ Problem still there ?

3. Run MF and SIM in ADMIN MODE

4. Confirm Your electrical Setup. Any Diodes there.... Maby LED set iverted ? GRD and/or 5v is used from Arduino ? If Eyternal Power is used... Is it correct implement.

5. Confirm your Device Settings.
Get sure that you have not multiple Devices on the same Pin...
Good Luck !
