Unit #4-06

Learning Outcome

At the end of this lesson, you will be able to:

  • build a circuit with 1 transistor

Review

  • go over Single LED

Lesson

  • go over single transistor
    • the ones we have are not perfect, it will be low power and high power vs off and on
    • flat side away from you, when placing in the breadboard
      • then collector will be on your right and emitter on your left
    • Note: the transistor Base has a 4.7k Ω resistor

Activity

  • nil

Daily Assignment

  • circuit - "Single Transistor"
    • draw the diagram in Fritzing
      • ensure you give the file a proper name (like the title of the circuit above)
      • ensure you include 4 notes, on both the schematic and the breadboard views:
        1. the "Truth Table"
        2. the course code, your name and the title
        3. the Input(s)
        4. the Output(s)
      • ensure the wires in the schematic view are properly laid out
      • save the *.fzz file not only to your computer but also to your Google Drive
      • export the breadboard and schematic view and upload them to your notebook as 1 PDF
  • build the circuit on your breadboard
    • once working, call me over to check
    • take a picture of your completed breadboard and upload it to your notebook
  • Note: you should be uploading 3 things to your notebook, in a single document:
    1. breadboard drawing
    2. schematic drawing
    3. picture of completed real world breadboard

Extra

    • if you finish early, move to next circuit

Watch video from:

  • 0:00 to 2:21

Note: He is using a push button and we use a 2 way switch. When the button is not pressed, the circuit is completely broken. This NEVER happens inside a computer. When it is a logical "0", the input is attached to ground "-", not just not connected.
