![]() So, what are you waiting for, go and get your first prototype order for free. Besides this the new members also get a 5 dollars Coupon balance. Feel free to visit their website JLCPCB to not only find out what awesome PCB and Assembly services they offer, but also to easily upload your Gerber files and thus order affordable and highly quality PCBs quickly. The PCB board used in this project is sponsored by JLCPCB. $2 for 1-4 Layer PCBs, sign up to get $18 new user coupons. You will learn a lot of new things in this article, like for example, how to control the speed and limits of the stepper motor using the sliders, how to manually adjust the starting position of the stepper motor using a potentiometer, and how to control a stepper motor using the Joystick on the blynk application.īefore, I am going to explain how to make your own small size and low cost wireless Bluetooth controlled Stepper Motors controller, first a few words about the sponsor for sending me such high quality PCB. I have also used the same CNC shield with the Nodemcu ESP8266 Wifi Module this way the two Hybrid Stepper motors can be controlled from anywhere around the world using the cell phone application designed in Blynk. If you are a beginner and you have never used the CNC shield then I highly recommend read my previous article which also explains how to control the speed and direction of the stepper motor automatically and then how to use a joystick to control a stepper motor. In my previous tutorial “ Arduino CNC Shield V3.0 and A4988 Hybrid Stepper Motor Driver + Joystick” I used the CNC shield with Arduino and covered the maximum basic things including the technical specifications and how to use the male headers and how to use the CNC shield in custom made projects. I will only use an android cell phone application. In this project, I am not going to using any keypads or touchscreen for entering the direction, speed, and limit values. To control different complex processes we usually enter different parameters using keypads or touch screens which greatly increases the project overall cost. The A4988 Stepper Motor Drivers and the Nema17 Bi-polar Stepper Motors are becoming very popular and this is the reason they are frequently used in CNC machine, handwriting machines, 3D printers, etc. ![]() Stepper Motor Arduino Code Explanation:Ĭontrol Position and Speed of Stepper Motor:Ĭontrol Position and Speed of Stepper Motor using Android Bluetooth App, A4988 Driver, & Arduino- I have been using Unipolar and Bipolar Stepper motors for quite a long time in different beginners, intermediate, and advanced level projects.Bluetooth Controller Stepper Motor Arduino Code:.A4988 Stepper Motor Driver Breadboard Testing:.A4988 Stepper Motor Driver Interfacing with Arduino:.A4988 Stepper Motor Driver Specs & Pinout:. ![]()
