Today, I worked with a bread board. It was mostly a refresher, as I already learned how to use a breadboard last year. I refreshed my memory about where to connect wires and about how important where you insert a wire is, as misplacing it could make the entire thing not work. Something new I learned was “female wires”. Last year, we only worked with “male wires” but this year, I was introduced to female wires. The female wires really extended the many things you could do with the wires. The last thing that I learned about were batteries and battery holders. Last year we did not work with them, so they were very foreign to me; however, I soon realized how important they were in providing power for the circuits.
