3.1.1

Activity 3.1.1 Inputs and Outputs

1. Examine the wire diagram on the mini switch and describe how the diagram relates to the concepts of normally open and normally closed.

2. If computers only understand digital signals, then how is a computer able to interpret the analog signals coming from the interface?

3. Why does resistance decrease as the NTC Resistor becomes warmer?


Mini Switch:
-when plugged into 1 and 3 and not pressing button:
unchecked
at zero
not present
-when in 1 and 3 and pressed
checked
at one
present
-when plugged into 1 and 2 everything is flip-flopped

Potentiometer:
-range: 38-4945

NTC Resistor:
-1668
-while warm was at 1318
Motor:
-one way to change the direction of spin is by switching the wire ports

Electromagnet:
When reed switch is touched the box becomes checked

Photo transistor:
-closer light gets the number goes down

3.1.4

Today, Wednesday, we used ROBO PRo once again. Today we started working with switches and it actually became a little harder. We got it under control and were able to do it. Here is our picture of a light with a potentiometer. When you turn the potentiometer, the light will turn on. Pretty cool stuff.

My team consisted of Ryan, Nick, and I. Although we used the software on my computer, we all helped to built the module and take pictures. I think all of us made an even contribution.
Questions
1. Describe why it is important to include branches in programs
-----It is important to include branches in your program because if you want to be able to turn things on and off, you need to have switches and branches in your program.

2. Describe an everyday application of a normally open switch that has not been given as an example.
 ----An everyday application of an open switch is a railroad switch. When you turn the switch it changes to a different track.

3. Describe an everyday application of a normally closed switch that has not been given as an example.
------A normally closed switch would be a faucet. When you open the faucet the water will flow.

Sub Programs Blog

 Above is a picture of my sub  program, the same pragram we designed yesterday. Below is a picture of my main program. As you can see my sub program (Bisquick) is nested withen my main program

Flowcharting



1. How is flowcharting similar to using a map to plan a route for a trip?
- Flowcharting is very similair to using a road map because each arrow represents a road. Each box represents a turn or curve in the road.
2. Describe a process that you perform every day. Develop a flowchart that illustrates the process.
-I did a flow chart of my morning

Survival At Sea Game

In this activity we broke into groups and were given the assignment to rank items in order of importance while lost at sea.
My Picks
Top Picks:
1. A 25 L container of water
- I chose this because it is impossible to survive without water after 2 days and it is likely that you will be lost at sea for over 2 days.
2. A case of Army Rations
- After water food is probably the most important thing to stay strong and to keep have energy.
Last Picks:
14. One bottle of 160 percent proof Rum
- I didnt think rum would come into play while at sea, I thought it was not as important as most of the other things
15. 2 Boxes of Chocolate bars
- chocolate bars could provide sugar, but the effectiveness of two cases would not be enough to make a difference.
Teams Picks
My team agreed on the top pick, water, because it is essential for survival in any condition
We disagreed on the 15ft of Nylon rope, i ranked it 10 and my team ranked it 5. I thought 15ft wasn't really enough to do much with, i wasn't really sure what i would use it for.
Our group worked well together and came up with uses for each item. We were very productive with the amount of time given.
Experts Picks
The top picks betwen our group and the Coastguard were off a little. Items like the shaving mirror, ranked first by the coast gaurd, were ranked by us late. I also disagreed signifigantly with the coastguards ranking of the fishing kit. Their argument was that it was risky, but I think if you are in such a situation as desperate as lost at sea, I think risks are necessary in surving these situations.
