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 ...
