Mary Stepho's Blog Week 12

1) This is the computerized version of my Circuit Schematic

2) Here are more in depth pictures and both of my attempts with 1 failed attempt.

This is my circuit from the left.

This is my circuit from the front.

This is my circuit from the right.

Here is a video showing my first attempt which failed. The switch, displays, op-amp, relay, and LED, and photocell, and transistor work fine. I came to realize that my motor wasn't connected correctly. I placed one of its end in the power supply when it was supposed to go to ground.

Failed attempt as explained above.

This is my second attempt which was a success, because I fixed my earlier problem of the error in motor connection to my breadboard.

Successful attempt as explained above.

3) There were 2 tricky things I had to figure out in this lab. One was how was I going to be flashy at the end, because I am the last person, and how was I going to make everything work.

I addressed the first problem with Kaya. I decided instead of knocking down domino's to spell out 393 I would instead make a rig that will let out a helium balloon. I am still in the process of designing that rig, but my circuit works perfectly.

The second problem was how was I going to make all of these components work with one another. I decided to list all of the components I wanted to use, and then went back to previous weeks as referencing to what I was using. This helped a lot because it reminded me of how these components like the photocell or relay, etc..., are set up. So then I mimicked those blogs and made it fit my personal circuit and that solved my second problem.
