Today we are driving high current high voltage applications using only a microcontroller and relay. To accomplish this, we are going to take a closer look at a few different types of relay modules you might find across the Internet. We will first go over the components and connections available on each module, then we will go over the schematic to get a better understanding of how each module works, and finally we will demonstrate how to connect these modules into our circuits. Throughout this video I will touch on important considerations to mindful of to ensure you don’t damage your microcontroller or worse the item connected to the relay. • 00:00 Intro • 00:39 Hardware Overview • 02:56 Relay One Schematic • 06:22 Relay Two Schematic • 07:53 Relay Three Schematic • 08:20 Demo with External Power Supply • 09:52 Demo without External Power Supply • 11:19 Recap • Hardware: • SainSmart 2 Channel Relay: https://amzn.to/3l74TXi • HiLetgo 5V High/Low Relay: https://amzn.to/3crUelR • Tolako 5V 1 Channel Relay: https://amzn.to/3vlcWUU • Elegoo Uno Project Kit: https://amzn.to/3uq6YSd​ • Breadboard: https://amzn.to/2Npu9f5​ • Elegoo Uno R3 Board Only: https://amzn.to/3dCMpMA • Helpful Links: • http://www.arduino.cc​ • http://www.sparkfun.com​ • http://www.adafruit.com​ • http://www.mouser.com​ • http://www.digikey.com
