Welcome to the Ultimate Guide to Arduino Automation! In this 20-video series, you will learn how to automate equipment using Arduino compatible devices. You will learn how to read sensors, control motors, automate devices, and display information on LCD’s and touch screens. As you watch these videos, you will unlock new automation skills that will bring your Arduino Automation projects to the next level.

Source Code and Schematics for all 20 lessons are available here: sciencefuninnovation.gumroad.com/l/sdehee for a small fee that will allow this channel to continue making great content.

In Lesson 1 you will learn how to switch on and off both DC and AC powered devices using an Arduino using the digitalWrite() command.
