# 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.

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)
