How to Stop, Reverse & Home Stepper Motors with Limit Switches

Video Description

In this Arduino stepper motor tutorial, I’ll show you how to use limit switches with Arduino to control the boundaries of your stepper motors—perfect for automating sliding camera rigs, CNC machines, and any other project that needs precise start and stop points. Here’s what I’ll cover: - What limit switches are and how they work - How to wire them to an Arduino Uno - Three step-by-step code examples: 1. Stop the stepper motor when a limit switch is triggered 2. Reverse the stepper motor’s direction when it hits a limit switch (like a camera slider) 3. Home the stepper motor at startup, so it always starts in the same position This Arduino tutorial is great for beginners and anyone looking to build reliable, automated projects with stepper motors. 🔗 Full Tutorial & Wiring Diagrams: https://racheldebarros.com/using-limit-switches-with-stepper-motors-and-arduino/ 🔗 NEMA 17 Stepper Motor with Arduino - Complete Guide: https://racheldebarros.com/control-nema17-with-a4988-arduino-wiring-and-code-guide/ 🤖 WANT MORE Arduino projects with wiring diagrams and code?
