wifi-stepper-motor-controller's Introduction

WiFi Stepper Motor Controller

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

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 library, so please follow this procedure: From the Arduino IDE menu:

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