  1. ECE 002 Final Project By Brandon Minor, Adam McCormack, Benjamin Miller, Damon McCullough

  2. Group 11 was undoubtedly one of the most capable groups. True, they had some tough times, but they always knew what to expect. Their preparedness made up for their tardiness; for this reason, they never were late with a report or an assignment, though they might have been late themselves. Team Beardface

  3. Projects This Semester • Sensor Characterization • Instrumentation Lab • Elevator Project • Circuits Lab • PSPICE Lab • MATLAB… Lab…

  4. Learned how to use Oscilloscope and Multimeter Instrumentation Lab

  5. Senors are devices that receive signals from the outside world and use the data to perform useful functions in everyday electronics. • Light • Movement • Color • Weight • Etc. SENSOR CHARACTERIZATION

  6. Light Sensor The light sensor is used to interpret light values, more specifically the brightness levels of the surrounding environment. Higher values are dark and low values are light/whiter. /* Light Sensor Program*/ void main() {   int light;   while(start_button()==0) { }   while(1) {     light = analog(6);     printf("The digitized light value is %d\n", light);     sleep(1.0);     printf("\n");   } }

  7. Sonar Sensor The sonar senor also detects distance but for a much longer range. The range is from 30 - 2000 mm. Small values mean the object is close and large values means it very far away. /* Sonar Sensor Program*/ void main() {   int range;   while(start_button()==0) { }   while(1) {     range = sonar();     printf("The digitized range is %d\n", range);     sleep(1.0);     printf("\n");   } }

  8. Optical The optical range finder sensor detects distance. Low values are very far away objects and high values are very close objects. The range is very small, only about 8 inches. /* Optical Rangefinder Sensor Program*/ void main() {   int range;   while(start_button()==0) { }   while(1) {     range = analog(6);     printf("The digitized range is %d\n", range);     sleep(1.0);     printf("\n");   } }

  9. The Top sensor measures brightness. High values signify darkness and low values mean light. IR Top Hat Sensor

  10. Our group encountered some problems while implementing the experiments • Top Hat Sensor not giving accurate readings at first • We realized that we had the sensor plugged into the wrong port • Handy Board had trouble loading the programs • All these problems made us more aware of testing and triple checking our data to make sure it is accurate. Conclusion

  11. The elevator project was used to learn about how to implement the sensors we tested in the last lab • to look at the possibilities of what sensor would do the job most effectively and efficiently • Since we only needed to known when the elevator was at the first or second floor, button sensors would do Elevator Project

  12. void main() • { • while(1) // 1 infinite loop • { • while(start_button()==0){} • while(1) // 1 infinite loop • { • if (digital(7)==1){ • motor(0,9); • } • if(digital(10)==1){ • motor(0,0); • } • if(digital(9)==1){ • motor(0,-9); • } • if(digital(8)==1){ • motor(0,0); • } • } • } • } Elevator Program

  13. Used MATLAB to solve a complex circuit MATLAB

  14. y x b a • MATLAB was also used to integrate a function using the trapezoidal rule • Vectorized Integration > Composite Integration f(b) f(a)

  15. We soldered wires together and followed a schematic to assemble an AM radio. The end result was beautiful sound from an AM radio station. AM RADIO

  16. The purpose of this integrated lab was to learn how to calculate commonly used values in circuitry, such as current and voltage, by using a multimeter. Groups also learned how different parts in a circuit can affect these values. Circuit Lab

  17. Lab involved becoming acquainted with computer aided circuit design • Circuit simulations PSPICE Lab

  18. A whole bunch • Group 11 learned many things, and found even more that they have to improve upon. They could work more efficiently together by distributing work, but sometimes this left some members clueless as to what was actually going on, what the big goal of the project really was. • In the future, the group should distribute work in cycles, somebody doing this one day and that the other, so that everyone comprehends every process involved. • Also, the group should work on its soldering skills. But that just takes practice. What we learned…
