Group 4 Final Presentation

• Group Alicia Chau, Shawn Chawla, Melissa
  Delgado, Christina DeMerville

2
Sensor Characterization

• Chose two sensors, characterized as analog or
  digital and wrote corresponding program.
• Downloaded program to handyboard.
• Collected the data outputted on the screen of
  handyboard.
• Sensors used light, sonar

Sensor Characterization-Results
4
Robot/Maze Navigation Project

• Build and program a robot to maneuver through a
  maze.
• Allow the robot to decide for itself which
  direction to turn.
• Sensors used touch, sonar
• Difficulties in integrating entire program,
  turning, and using sensors.

5
Robot/ Maze- section of program

• while(start_button()0)
  //does nothing until start button is pressed
• while(1)
  //continuous while loop
• flag1
  //sets flag equal to one
• light1 analog(4)
  //sets integer to read value from analog
  sensor
• light2analog(1)
  //sets integer to read value from analog
  sensor
• sonsonar()
  //sets integer to read value from sonar
  sensor
• touch digital(10)
  //sets integer to read value from digital
  sensor
• while(flag1)
  //enters while loop

6
Working with the Oscilloscope

• Learning to use the various settings and
  capabilities of an oscilloscope.
• Altering shape, frequency and altitude
• Materials oscilloscope, cables
• Difficulties plugging in cables

7
Elevator Project

• Construct an elevator made of legos with two (or
  three) floors, and a cart.
• Materials touch sensor, handyboard
• Difficulties using sensors, writing program and
  building the structure.

8
Elevator project- part of program

• while(start_button()0) //nothing
  happens until start button is pressed
• while(1)
  //enters a continuous while loop
• if(touch21 level 1)
  //sets a condition elevator on floor 1 and floor
  2 button is pressed
• levellevel1
  //changes level to 2
• while(lightlt200)
  //elevator goes up while this is true
• motor(1,50)

9
Circuits Lab

• Learn to construct circuits, measure current,
  voltage of unknown resistors, and voltage drops.
• Materials breadboard, resistors, diode, power
  supply.
• Difficulties getting accustomed to using
  breadboards and diodes.

10
PSPICE Lab

• Learn to simulate a circuit using PSPICE program.
• Materials computer, program
• Difficulties learning to use PSPICE

11
Circuits Lab- results
12
MATLAB HW

• Objective was to use Matlab to solve an
  unbalanced Wheatstone bridge.
• Materials computer, program.
• Learned the simplicity in using Matlab versus
  computing output by hand.

13
MATLAB Code used

• A 300 100 150 100 650 -300 150 -300 450
• V 0 0 24
• I inv(A)V

14
Conclusion What Weve Learned

• Relationship between software hardware
• Importance of troubleshooting
• teamwork
