WiFi Stepper Motor Controller

Control Stepper Motor remotely using WiFI using ESP8266, DRV8825 and the Blynk App

NOTE: THIS PROJECT IS DEPRECATED!!!

Since Blynk upgraded to v2 and removed v1 from the AppStore and the PlayStore, there is no reason to use it and I leave it here just as a reference for the history.

I created a new project that replacing this one and it can be found here: https://github.com/tamirrosenberg/WiFi-Stepper-Motor-Controller-v2

Please follow the new project - Thank you!

DEPRECATED - YOU CAN STOP HERE!!!

The Project

Tuning the Magnetic loop antenna, by controling the capacitor remotely, using Wifi. I built a Magnetic Loop Antenna, and my idea was to control the tuning capacitor remotely.

Please visit my YouTube channel to see this project in action

This project is based on:

• ESP8266 Micro Controller
• DRV8255 Stepper Motor Driver
• Bipolar stepper motor
• Blynk Application

The Blynk App

In the Blynk app, I added five virtual buttons:

• V0 - Tune Left
• V1 - Tune Right
• V2 - Fine Tune Left
• V3 - Fine Tune Right
• V4 - Scan

DRV8825 - Motor Driver

The DRV8825 is a smart motor driver that can be used with normal steps and even with micro-steps, and that can be controlled by the driver's pins M0, M1, M2. In my case I wanted to use the 1/32 micro-steps, and these are the speeds that you will see in the code. More details about this driver can be found here: https://www.pololu.com/product/2133

Arduino IDE

When you are using the Arduino IDE, you will probalby need to install the Blynk & ESP libraries, so please follow this procedure.

1. Go to the "File" menu and choose "Preferences"
2. In the "Additional Boards Manager URLs:" insert "http://arduino.esp8266.com/stable/package_esp8266com_index.json"
3. Confirm with "Ok"

From the Arduino IDE menu:

1. Go to "Sketch" --> "Include Library" --> "Manage Libraries"
2. Search for "Blynk", and install it

Choose the correct ESP library:

1. In your Aruduino IDE, from the main menu choose "Tools"
2. Then choose Board "NodeMCU 1.0 (ESP-12E Module)
