🚀 Microstepping Your Stepper Motor | Increase Precision & Smooth Motion.

🌀 How to Do Microstepping with NEMA 17 Stepper Motor | DRV8825 + Arduino UNO Tutorial In this video, I’ll show you how to control your NEMA 17 stepper motor using microstepping with the DRV8825 stepper driver and Arduino Uno. Microstepping allows smoother motion, higher precision, and reduced noise — perfect for robotics, 3D printers, and CNC projects! 🔧 Components Used: 1. Arduino Uno 2. DRV8825 Stepper Motor Driver 3. NEMA 17 Stepper Motor (1.8° step angle) 4. 12V DC Power Supply 5. Jumper Wires 6. 100µF Capacitor (across VMOT and GND for protection) ⚙️ Microstepping Settings (DRV8825 MS1, MS2, MS3 Pins) Microstepping Mode : MS Pins MS1 MS2 MS3 Full Step LOW LOW LOW 1/2 Step HIGH LOW LOW 1/4 Step LOW HIGH LOW 1/8 Step HIGH HIGH LOW 1/16 Step LOW LOW HIGH 1/32 Step HIGH HIGH HIGH ⚡ Arduino Code: // Microstepping control of NEMA 17 using DRV8825 and Arduino Uno #define dirPin 2 #define stepPin 3 #define MS1 4 #define MS2 5 #define MS3 6 void setup() { pinMode(dirPin, OUTPUT); pinMode(stepPin, OUTPUT); pinMode(MS1, OUTPUT); pinMode(MS2, OUTPUT); pinMode(MS3, OUTPUT); // Set microstepping mode (example: 1/16 step) digitalWrite(MS1, LOW); digitalWrite(MS2, LOW); digitalWrite(MS3, HIGH); digitalWrite(dirPin, HIGH); // Set direction } void loop() { // Step the motor slowly to observe microstepping digitalWrite(stepPin, HIGH); delayMicroseconds(800); digitalWrite(stepPin, LOW); delayMicroseconds(800); } 🔍 Explanation: The MS1–MS3 pins control the microstepping mode of the DRV8825. Adjust the delayMicroseconds() value to control motor speed. You can also modify the MS1, MS2, MS3 values in code to switch between full, half, or microstep modes. Don’t forget to set the current limit on your DRV8825 using the potentiometer before connecting your motor. My Other Videos Link :- 1.
