Connecting a Relay Module to a Microcontroller

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
