Bluffing pin Arduino nano fake pin

Projects General Guidance

Hi there,
I am actually doing a food automation,

The code uses 87% space
I utilise all 6 analog and all 13 digital pins
Code uses every pins i can't use a mux.
Since it won't serve my purpose...

I need to use another aceelstepper library i dedicated one pwm pin for it but Library needs direction also .

I don't have a pin to to give for that since every pin is working at same time

Is there a way to do it since i don't need direction pin... please help....

Should I need to edit library
Also i can't use another Arduino or mega for upgrade my financial situation is very poor

There is no useful information in your post. For informed help, please read and follow the instructions in the "How to get the best out of the forum" post, linked at the head of every forum category.

Maybe use the onboard LED pin as "fake" DIR pin?

It is 13 digital pin but already i am using it for heater control

5

Swap for a board with more pins ?

UNO> MEGA

Or use pins 0,1 if not using serial or use one pin to select the function of some of the others .

I count 8 analogue pins and 12 free digital pins on a classic Nano.

Then simply connect the direction pin on the stepper driver to either ground or the 5V supply.

hi everyone thank you for the support finally figured out used an analoge pin connected for all my switch and freed a pin ..you can check out how to do it in https://electronics.stackexchange.com/questions/101409/how-to-debouce-six-buttons-on-one-analog-pin-with-arduino[link](https://electronics.stackexchange.com/questions/101409/how-to-debouce-six-buttons-on-one-analog-pin-with-arduino)

But you said:-

So how is this a solution?

By the way there is something wrong with that link, it gives a page not found.

Interesting solution.

The formatting of the link is not quite right, here it is:
