EE 40 Final Project Part I General instruction 1 The final project will count for 7 5 of your grade 2 This project is composed of a basic part and a creation part A circuit diagram will be provided for the basic part while no circuit diagram will be given for the creation part 3 Every effort must be made to team up as a team of 1 or 2 only under very very special circumstances and approval by head GSI is required for forming a team of 3 Please try to find your lab partners before hand One of your team members will keep the board and the components during the project period Try to protect your progress and keep it in a good condition 4 Every group will get a project kit with a piece of breadboard and all the components Please check with the component list in lab guide part V to see if the kit is complete Keep it in a good condition during the whole project We don t have many extra parts to supply if you lose any of them 5 The grading will be mainly based on the lab report and the circuit functionality Typed lab report is preferred Hand written is also fine but has to be neat and clear Please see part IV for more information on the lab report 6 Lab report is due by December 10 th We will have a final competition You may choose to enter the competition to display your work The competition will be held on Dec 10 2007 The professor and all lab GSIs will attend this reception competition and select the projects which exemplify work above and beyond the guide instructions Each group entering the competition must do a 5 10 minutes show and tell First place 1 team TBA Second place 1 team TBA Third place 1 team TBA Part II Basic Circuit Light Sensor 1 Function analysis Figure 1 Basic circuit diagram Part III Creation Portion For each question you have to provide a circuit diagram with components values design analysis including function analysis and value selection and measured results similar to your analysis required in the basic lab Please address all the important issues or difficulties you encounter in your design and experiment Please indicate if you realize the required function Even if you didn t realize the function completely partial credit will be given if you provide good detailed measurements and explanations and can explain what problems you ran into 1 Maintaining the basic function of the circuit add a buzzer to it to make it buzz with the red LED in phase When the red LED is on the buzzer should buzz when the red LED is off the buzzer should keep silent Note the buzzer will not work powered with just a DC voltage It is like a speaker and requires some AC signal within the range of human hearing a good range to try would be around 200Hz to 1kHz which is close to human speech 2 Make the LED flashing speed adjustable 3 Make the buzzer pitch adjustable 4 Maintaining the basic function of the circuit add another yellow LED flashing together with the green one but out of phase or with phase shift which means when green is on yellow is off and vise versa However when the red LED is on both green and yellow should be off Part IV Lab report 1 Basic circuit 100 pt Please report the result of each building block A 4 5 V DC power supply
