NOTE: In this project, you will find a new WiFi Stepper Motor Controller App for Magnetic Loop Antenna, that is replacing the old Blynk App (as Blynk upgraded to v2 and removed v1 from the AppStore and the PlayStore). This project is replacing the old project that is now DEPRECATED: https://github.com/tamirrosenberg/WiFi-Stepper-Motor-Controller/edit/main/README.md
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. And it's working great! :)

WiFi Stepper Motor Controller App for Magnetic Loop Antenna (Blynk replacement)
Build a Magnetic Loop Antenna with Remote Wireless Tuning - Practical Guidance
The original project with the Blynk App - DEPRECATED!!!
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.
NOTE: Please follow the directions in the following video on how to set the correct Voltage/Current on the motor driver BEFORE using it:

From vesrion 0.3.1-beta
, I introduced an easy and fast way to install the application without the need of the Arduino IDE:
0.3-beta
or older)0.3.1-beta
or newerThe Arduino IDE can be download from: https://www.arduino.cc/en/software.
When you are using the Arduino IDE, you will probalby need to install the esp8266 libraries, so please follow this procedure:
Now, let's install and choose the board. From the Arduino IDE menu:
Now, we need to install few libraries that are in use and needed in the code, it's easy.
Please go to each of these links, and download the files to your computer by using the Green button called "Code" --> "Download ZIP":
Once you have all these files locally, go back to the Arduino IDE:
Now you are ready to install the code into the esp8266 micro-controller:
You just finished to installed the app and it's ready for use! YAY!!!
Are you allowed to use this code anywhere? Or change the code?
Yes, as long that it's for YOUR OWN PERSONAL USE (NOT FOR SELLING IT)!
