  2. Introduction Electricity/Electronics Engineering 1-2 Engineering01/EE/EE_presentation.pptx

  3. Objectives: Students will be able to… • Identify and describe the following components • Describe basic electronic theory • Identify schematic symbols for the above components • Use Ohm’s Law to calculate voltage, resistance, or amperage • Correctly identify a resistor's value and tolerance using resistor color code • Build simple to complex circuits following written directions and circuit schematics • Diode • SCR • NPN Transistor • PNP Transistor • Transistor Oscillator • Solderless Breadboard • Resistor • Photocell • Capacitor • Speaker Engineering01/EE/EE_presentation.pptx

  4. Evaluation Engineering01/EE/EE_presentation.pptx

  5. Expectations and Rules Write the following in your LRB • Yes, it is possible to test a 9V battery with your tongue or metal braces but not in this class • Do not write in the EKI Discover Electronicsbooks; • Do not touch other team’s components, parts, kits, etc. If you do; “Kick him out!” • Do not damage materials • If you do accidently burn out a component, let me know and Iwill replace it • If you do not report damaged materials it will be suspected it was done intentionally; “Kick him out!” Engineering01/EE/EE_presentation.pptx

  6. Lab Record Book • Record the following in your LRB. • Draw and label the schematic for each lab • Describe what you saw • Describe what caused what you saw • How is this component typically used • Google if not in the book Engineering01/EE/EE_presentation.pptx

  7. Teams • You will be working in teams of two • For all labs you must alternate building the circuit • You may guide another person when it’s their turn but you must not do it for them. • You may help the team member constructing the circuit but you may not do it for them • Each team member is responsible for their own LRB • Teams will consist of two students selected by your instructor randomly • Team selection using gradebook • Form teams and sit together Engineering01/EE/EE_presentation.pptx

  8. Assignments • We will do the first 3 lessons and 9 experiments together • You should be able to complete 2 experiments per day • Remember to alternate who actually does the lab (Teamwork) • Be prepared for short entry task quiz each day • No talking • Dividers • Eyes on your own paper • You can use your LRB for the quiz. Write stuff in it! Engineering01/EE/EE_presentation.pptx

  9. EKI Kits • Use inventory sheet provided to inventory the components of your kit • Lay the components on the picture depicting it • Have your instructor initial your sheet when finished • Report any discrepancies to your instructor and record on your inventory sheet • Also include your names, date, period, and kit number • When finished: • While waiting for other teams to inventory their kits, look through the Discover Electronics book to see what we will be covering and how it’s organized. • Read the Introduction on page 3 Engineering01/EE/EE_presentation.pptx

  10. Inventory Engineering01/EE/EE_presentation.pptx

  11. Kit Organization • When storing your kit it should look like this… Speaker, breadboard, and battery Book at bottom Zip lock bag of components Engineering01/EE/EE_presentation.pptx

  12. Lessons 1-3 Basic Electronic Theory, Resistor Color Code, Using the Solderless Breadboard Engineering01/EE/EE_presentation.pptx

  13. Lesson 1: : Basic Electronics Theory • Comparing water systems to electronic theory is a good analogy to help understand Voltage (water pressure), Amperage (water flow), and resistance (valve/faucet) • Insure students understand it is only an analogy, it does not reflect what is actually happening • For all “Pencil Exercises”, write the questions ANDanswers in your LRB • Read Lesson 1 and do Pencil Exercises 1 & 2 Engineering01/EE/EE_presentation.pptx

  14. Lesson 2 & 3 • Resistors, Resistance, Ohms • Read and do pencil exercises 1 & 2 • Using the Solderless Breadboard • Demonstration • Read then record the question and answer in LRB for the following: • “What happened to the LED when you made that change?” • “Explain why.” • Draw and label five rows of the breadboard • Circle the holes of one row which are connected to each other Engineering01/EE/EE_presentation.pptx

  15. Experiment 1 • How a Resistor Works • Draw and label the schematic • Record your Results and Observations • Draw and label the schematic for each lab • Describe what you observed • Describe what caused what you saw • How is this component typically used • Google if not in the book • Homework • http://hyperphysics.phy-astr.gsu.edu/hbase/electric/watcir.html Engineering01/EE/EE_presentation.pptx

  16. Experiments 2 -3 How a Potentiometer Works, How a Photocell Works Engineering01/EE/EE_presentation.pptx

  17. Experiments 2-3 • How a Potentiometer Works • Complete the reading and lab • Record your Results and Observations • Draw and label the schematic • Describe what you saw • Describe what caused what you saw • How is this component typically used • Google if not in the book • How a Photocell Works • Complete the reading and lab • Add required information to your LRB Engineering01/EE/EE_presentation.pptx

  18. Potentiometers vs Rheostats • Similar but different • Pots • Three leads: negative, positive and resistance • Always on • Examples • Wiper blades • Volume control and many other audio controls • Joy sticks • Rheostats • Two leads: negative and positive • Can be turned off • Examples • Heater controls • Dimmer switches • Motor speed controls Engineering01/EE/EE_presentation.pptx

  19. Experiments 4-5 How a Capacitor Works and How a Speaker Works Engineering01/EE/EE_presentation.pptx

  20. Experiment 4 • How a Capacitor Works • Think of a capacitor as a small can which collects electrons and store them until voltage is remove at which time the electrons move back out of the can like a small battery • Compare Figures 1-3 at right with those in the book • Draw Figures 1-3 at right in your LRB • Make LRB entries Engineering01/EE/EE_presentation.pptx

  21. Experiment 5 • How a Speaker Works • Add required information to your LRB • Homework: Read the article and watch the following video online at home - http://www.physics.org/article-questions.asp?id=54 Engineering01/EE/EE_presentation.pptx

  22. Experiments 6-7 How Diodes and SCRs Work Engineering01/EE/EE_presentation.pptx

  24. Experiments 8 & 9 How a NPN and PNP Transistors Work Engineering01/EE/EE_presentation.pptx

  25. Experiments 8 and 9 • How an NPN Transistor Works • Complete reading and lab • Make LRB entries • How a PNP Transistor Works • Complete reading and lab • Make LRB entries Engineering01/EE/EE_presentation.pptx

  26. Ohm’s Law Topics: Voltage, Current, Resistance Assignments: Video Notes, Quiz Engineering01/EE/EE_presentation.pptx

  27. Project "Do Your Own Thing” (It’s Hippie School!!!) • Select two experiments from A10 – A30 • Take turns adding components • You have 5 days to complete the two experiments • Work with your partner to complete them • Draw and label the schematic for each experiment • Have your instructor view each experiment as you finish them • Take photos of construction and video of the circuit working for your presentation. Engineering01/EE/EE_presentation.pptx

  28. Do Your Own Thing (cont.) • Two experiments are required but you may do more if you finish early. • Five extra-credit points awarded for each extra experiment up to three extra experiments Engineering01/EE/EE_presentation.pptx

  29. Presentation • Title slide: Name(s), Date, Period, Class (1 slide) • Prepare a presentation of the two experiments and any extra credit experiments you completed (14 slides minimum) • for the Basic E&E final unit experiments • Show schematic with parts labeled (1 slide) • Photos of construction with brief descriptions of parts and what they do (min. 5 slides) • Video of working lab (1 slide) • Discuss the problems you experienced and their solutions • Conclusion (1 slide) • 3-4 sentences reviewing what you did, learned, and results (success, fail) • Total Slides = 16 min.
