Help I need to fix my code!

I need to make both mortors move in opposite directions but i keep getting errors help?!?!?

Welcome to the forum.

@dandry

but i keep getting errors help?!?!?

So copy and paste the errors you get.

You might want to look at this How to get the best out of this forum before you proceed any further.
We only know what you tell us, and without knowing what you have, we don't stand a chance.

Also in embedded programming code is only half the story, we need to see a schematic to know how this is put together. It looks like from the code that you drive the coils direct from the Arduino. If so they can't supply enough current to drive a stepping motor.

You have also not included any libraries in the code you posted. Therefor myStepper is not defined.

when i compile your code, i see that myStepper and myStepper1 are not defined, there definitions are missing a type.

there's no #include for a stepper motor library to know the type for the library being used such as AccelStepper.

most experienced developers start small and test each new feature of the code rather than write a lot of code and then start test/debugging.

i suggest you start with one of the examples, Multistepper

Hi, @dandry
Welcome to the forum.

Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.

What model Arduino are you using?
Can you please post links to data/specs of the motors and the drivers?

Thanks.. Tom..
