How to Directly Drive x.27 or x.40 Stepper Motors

Caution

This tutorial is obsolete. See the updated documentation to learn how to use stepper motors with MobiFlight.

For this tutorial, you need the following components

• MobiFlight Connector
• MobiFlight Compatible Arduino with the newest MobiFlight Firmware
• x27 Stepper (Singleshaft) and/or x40 (DoubleShaft) Stepper
• Soldering Iron, Soldering tin, wires

Connect the wires to consecutive pins in your Arduino:

Go to "MobiFlight Modules"

Add a new device (Stepper Motor), then configure the pins, so that Pin 2 and Pin 3 are swapped:

It is important to have these two pins swapped otherwise the stepper will just buzz around angrily.

Under "Output" create a row, and name it what you'd like. Don't forget to check the active box.

Configure the stepper to whatever you'd like.

Under display, choose your stepper and insert your sim/stepper value. For me I found moving the stepper 729 steps gives 360 degrees of motion. The stepper has 315 degrees maximum so I set this as the test value.
