Blinking Led Circuit

For this circuit, we wired up a blinking LED(light emitting diode). We were able to change up the code, essentially speeding up and slowing down the frequency at which it blinks.

Circuit 2

Potentiometer Circuit

In this level, we made an adjustable blinking LED. The potentiometer was able to change how fast or slow it blinked. The fastest setting was a solid light, and the slowest was an extremely slow blink.

rgb led circuit

This circuit was very similar to the first circuit, but we used and RGB LED. This type of light changes colors instead of blinking. By changing the brightness of each color, we could make almost any color.

Multiple led circuit

In this circuit, we made a loop of light. When the lights were in one line, it looked very out of sync and random, but when we put the red lights on one side and the yellow ones on the other, the light travelled around the circle.

push buttons circuit

This circuit was very interesting. When we pressed either of the buttons by itself, the LED turned on, but when we pressed both at the same time, it turned the light off. The purpose for this in the real world is for safety, because in dangerous systems, you would not want a button pressed accidentally. This makes it safer, because the chance at bothe buttons being pressed at the same time is low.

Photo resistor circuit

For this level, we made a light sensor, were the light would turn on when it got darker. We found out that you could change the brightness by changing how fast you covered the sensor. We had a lot of fun with this one, and made some interesting observations.

Temperature sensor circuit

This circuit's sole purpose was to test the temperature. Even after many checks and rechecks, we still got some pretty varied data. We didn't end up figuring this out. If we could go back, I would definitely redo this section.

Servo.MOV

Servo Circuit

In this circuit, we wired up a servo to spin. I thought it was pretty cool, because we were able to randomize it, so that it just shook randomly. It was cool to set it on the desk and let it move itself around.

Buzzer.MOV

Buzzer Circuit

This buzzer circuit was able to create music through a little tiny buzzer. It was interesting how the music quality changed when we covered the piece up. It would get louder and smoother when we covered it, and it would get higher and shriller when left alone.

Motor circuit

This circuit was my personal favorite. We created the circuit, and then decided to use the motor as a Beyblade. Then, we connected the wires to a button and then directly to the ground and 5 Volt, which drew so much power that it would turn off the monitor we were using.

Relay circuit

In this one, we made two blinking lights that were connected, so while one was on, the other was off. We changed the code so that it went as fast as it could, but the relay and the diode next to it kept heating up. The sound from the relay switching was also pretty cool.

Shift register circuit

My favorite part of the shift register circuit was the cool shape of the shift register. It looked like a caterpillar or centipede. It was also cool how the lights all worked together to make it seem light the dot of light was traveling from one LED to the next.
