Well yes thank you.
So A0 on the board is pin 55 and so on
Also will a stepper motor run off these analog pins?
Thanks again

NO. Digital Pins are numbered 0-53 .... So its just logical that Pin A0 is represent by the NEXT free Number..... And thats 54!


About Motors.... We test the Analog Pins with LED and Buttons.... Simply test yourself if Motors work..... In theory yes.... But we can not garantee without own testing !
Good Luck !

OK thanks for that and your quick reply
I did not want to plan for 4 more stepper motors on the board if I could not use the Analog pins but I will swap some of the pins around if need be

Hi I just tested and I can report that a Stepper motor will run off the Analog pins on the Mega
So thanks for pointing me in the right direction regarding the numbering

Fine

Just NOTE: 4 Steppers is way to much for a Mega ! You can controll them without trouble BUT you can not power them. If you use so many Outputs get sure you power the Motors via a external device DIRECTLY ..... So it will also not work if you use a external Suply for the Mega..... Use it direct on the motor and just combine the GRD from that device with the Mega to get the same potential !
Good Luck !
