Ivan-AM-20-explored classes to enroll in Instructables and Udemy

Today i spent my 20 minutes of free lab time searching for a class to enroll in. I finally found a circuit board design class that looks interesting and related to what we are learning. The link for that class is https://www.instructables.com/class/Circuit-Board-Design-Class/. I also found an arduino class, the link for that is https://www.instructables.com/class/Arduino-Class/. When I went on to the the Udemy website i was looking for free classes. All of the classes i saw were $9.99 and there was no free option button in sight. Hopefully next time I visit this website I'll figure it out or someone else will.
