This circuit is perhaps one of the simplest circuits. It includes turning an LED light on and off. It only uses a few components, and the video below includes an extra LED light that I added in effort to explore how the Breadboard works.

This circuit is similar to circuit 1, however, one can change the brightness of the LED light using a potentiometer. Potentiometers are very common in our lives, and they can be used in things such as adjusting volume in a car or in a video game controller.

This is an LED that can be changed to any color on the RGB (Red, Green, Blue) spectrum. The code below shows how the colors are changed and how it flows from one color to another. RGB LEDs are extremely common, as they are used in any screen, and they use the same basic technology that pixels on a screen use.

This circuit uses 8 different LEDs and it turns one on while turning the one behind it off. We had trouble getting this circuit to work since there were a lot of parts to it, and one LED wasn't working, so we switched around a few resistors and it ended up working.

This circuit is similar to the potentiometer circuit, in the way that they can both be influenced by a person. In this circuit, a person can press one button to turn on the LED light and the other to turn the LED off.

This circuit uses a photoresistor to check light levels. If there is no light, the LED will turn on, if there is a lot off light, it will stay off. This works the same way that nightlights do, they turn on when it is dark.

This uses a temperature reader to determine the temperature of the air around the unit. This has various uses and is used in anything that can tell you the temperature.

This circuit includes a servo motor. A servo motor rotates slowly and precisely, unlike a regular motor, which just spins quickly. Servo motors can be used in cars to control speed.

A buzzer is similar to a speaker, but it can only play simple notes, no words or anything. Buzzers can be used just to play things, like when a washing machine cycle is done.

In this circuit, we made a motor that could spin. Unfortunately, there was some bad wires so we could not get a video of it working

This circuit includes a relay, which changes the direction of electricity to alternate two different paths. In this circuit, we used it to flash LEDs on and off one at a time. Unfortunately, our wires were still messed up so it did not work.

In this circuit, a shift detector is used. A shift detector can turn 3 outputs into 8 while only using 3 pins. The shift detectors outputs can be coded to be on or off.
