1. 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

3. 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 {
flag=1; //sets flag equal to one
light1= analog(4); //sets integer to read value from analog sensor
light2=analog(1); //sets integer to read value from analog sensor
son=sonar(); //sets integer to read value from sonar sensor
touch= digital(10); //sets integer to read value from digital sensor
while(flag==1) //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(touch2==1 && level ==1) //sets a condition; elevator on floor 1 and floor 2 button is pressed
level=level+1; //changes level to 2
while(light<=200) //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 We’ve Learned
Relationship between software & hardware
Importance of troubleshooting
teamwork
