Sub Programs and Meter Displays

Main Program

Sub Program

• This activity was to use programing we just previously learned (increasing variables) and to apply it with subprogramming.
• The sub program contains all of the acutal work while allowing the main program to minimize and organize all the work it has.
• Also sub-programs can be easily copied and moved allowing work witht he main-program to be easier
  
  

Robo pro branch functions and variables

First it goes through a 1 second delay, then adds 1. If the variable does not equal 5 it will continue to go through this process of a 1 second delay then adding 1 until it reaches 5 and then the program will terminate.

Team Building with a Tennis Ball

Challenge:

• pass a tennis ball to each member of your team as fast as you can


• No constriants for first experiment


• For the second experiment only one team member can touch the ball at a time


• The third experiment only one team member may touch the ball at a time and each member has to be arms lengthen apart

The Plan:

• First Experiment: We all got into a circle and put our hands in the middle. Then using our hands that made the platform we created we just rolled the ball around.


• Second Experiment: We still stayed in a circle, but we just dropped the ball into each others hands.


• Third Experiemnt: My group stretched out the circle until we were arm lengthen apart and passed the ball around like we were playing hot potato

Execution:

• First Experiment:was fast and ver efficient
• Second Experiment: was efficient, but was at a moderate speed
• Third Experiment: Was pretty fast, but how we plaaned to pass the ball made it very inaccurate

Changes:

• First Experiment: I would make no changes becasue it was the fastest and easiest way to ge tthe ball around
• Second Experiment: I would change it to make the ball roll down our hands like a set of stairs
• Third Experiment I would keep the same set up, but toss the ball underhanded to make it more accurate so it doesn't go all over the place

Super Advertising

Super bowl ads:

• A normal 30 second super bowl ad costs around 2.7 million dollars
• throughout the game there are several commercials from the same company
• around 90 million people watch the super bowl each year

Is it worth it:

• Yes
• Well if an average car costs around $30,000 and profits from it are $10,000
• You need 270 people to buy a car of that amount to make up the cost single ad
• making the it pretty easy to earn move money they invested if 90 million people were watching

Flowcharts: Activity 3.1.2

1. How is flowcharting similar to using a map to plan a route for a trip?

• while driving on one highway you look for a specific exit or conjunction to the next highway
• You keep doing this until you reach the exit of your desired location

2. Describe a process that you perform every day. Develop a flowchart that illustrates the process.
