During the circuit unit, we talked about what a circuit was as well as actually getting to make one! We worked with a bread board and made different types of gates. Here's an image of it
This is a breadboard. We sed this to make either an AND gate or an OR gate. Here's a pictuere of both:
With the AND gate, BOTH switches need to be on in order for the L.E.D. to be on. With the OR gate, one or the other needs to be on for the L.E.D. to be on. In either gate, if both of them are on, then the light will be on and if both then of them are off then the light will be off.
We also worked with soldering which is when you take a very hot tube of metal and you melt another piece of metal on to it in order to melt it onto whatever you want to melt it onto. This is what we made with soldering:
This little guy isn't exactly what we made, it's just an example. We made a little dude that looks like the Andriod guy.
