Arduino Contact Switch Tutorial | Reed Switches, Micro Switches & Limit Switches
Explore the world of contact switches with Arduino — from magnetic reed switches to micro switches and limit switches. This tutorial covers how each type works, how to wire them as digital inputs, and real-world applications in robotics and automation.
🔘 What you'll learn and more things to explore:
• Reed switches: magnetic activation, door/window sensors
• Micro switches: precise mechanical activation
• Limit switches: end-stop detection for motors and robots
• Wiring all types as Arduino digital inputs with pull-up resistors
