Today we will learn how to use Transistors and MOSFETs to enable our Arduino to switch high-current DC loads, including a 12-volt RGB LED Strip Light. • Article at https://dronebotworkshop.com/transist... • More tutorials and projects at https://dronebotworkshop.com • Chat on the Forum at https://forum.dronebotworkshop.com • Join the newsletter - https://dronebotworkshop.com/subscribe/ • Transistors are the basic building block of modern electronics. Just about everything uses transistors, including the Arduino itself. • Using a power transistor or MOSFET we can drive high-current devices using the logic-level outputs from our Arduino. Today we’ll learn to use both devices. • We will start with a simple transistor switch, you’ll see how easy it is to switch a high-current DC lamp using a popular power transistor. • Inductive loads like motors and relays present an additional challenge, as these devices generate a “back-EMF” that we need to deal with. We’ll use a diode to take care of the back-EMF and build a simple motor speed controller. • We will then turn our focus to MOSFETs. MOSFETs have a number of advantages over standard transistors. We will learn how to use popular MOSFET modules to control an RGB LED Strip in a simple but colorful experiment. • Here is what is in today's video: • 00:00 - Introduction • 02:49 - Transistors and MOSFETs • 16:23 - Transistor Switching Demo • 22:54 - Transistor Motor Control • 29:52 - MOSFET RGB LED Strip Light Control • Please note that transistors and MOSFETs are great for controlling DC loads, but not AC. I’ll be showing you how to control AC loads in a future video.
