How to Use a Solenoid with Arduino

The video tutorial explains how solenoids differ from motors by providing linear motion. It covers the types of solenoids, including push, pull, and push-pull solenoids, and their applications. The tutorial details how to drive a solenoid using an Arduino and a transistor, specifically an N-channel MOSFET, to handle the higher current requirements. It emphasizes the importance of using a flyback diode to prevent voltage spikes and discusses the circuit setup, including power connections and safety precautions. The video concludes with a demonstration of the Arduino code used to control the solenoid, which is similar to the code for blinking an LED.

What type of motion do solenoids provide compared to motors?

• Linear or back and forth motion

• Vibrational motion

• Rotational motion

• Circular motion

What is a key consideration when using solenoids continuously?
