Nextion-X-StepperMotor

Control a Arduino stepper motor using a Nextion screen

Parts Used:

- Arduino Uno
- 28BYJ-48 Stepper Motor with Driver
- NEXTION NX4024T032 - GENERIC 3.2" Screen
- BreadBoard
- A bunch of Wires

Diagram

Setup

1. Follow the diagram above
2. Upload the TFT file to the Nextion Screen via a mico SD Card
3. Install all necessary libraries to the Arduino Editor
4. Upload the .ino file to the Arduino Uno(When uploading make sure that there are no wires in the Pins 0 and 1(Serial Ports) otherwise a error will show up)

Interface

- The blue text above is the current position of the motor
- Enter integers, fractions or both(using the SPC button)
- CAL or Calibration allows the user to change the current position without the motor turning
- The Setting button on the top right allows the user to go to the setting page and change the speed of the motor

Example

User: 1 1/4 -> Enter
Motor: Rotates a full Revolution and then a Quarter of a Revolution to get to the "1 1/4" position

User: 2 -> Enter
Motor: Rotates 3/4 of a Revolution to get to the "2" position

User: -1 -> Enter
Motor: Rotates back 3 full Revoultions back to get to the "-1" position 

User: 0 -> CAL
Motor: Does not rotate but it is at the "0" position

User: 1 -> Enter
Motor: Rotates a full Revolution to get to the "1" position

Update

Added the .hmi file so anyone can play around with the display
