Lab 0 part 1: Parts list and the nScope

Objective: Get your lab kit and make sure everything works.

Skills Learned: How to use a breadboard, wire strippers, and the nScope’s power supply and software.

  1. Open up your lab kit and make sure you have the following components :
    • resistor
    • capacitor
    • multimeter
    • nScope
    • wire stripper
    • wire bundle
    • LEDs
    • didoes
    • chips in foam
  2. Download and install the nScope application from
  3. Strip a wire: Use the appropriate hole in the wire strippers to remove 1/4” of insulation from both ends of a 2” long wire. Plug one end into a hole on the row labeled “A1” and the other into the row labeled “CH1”. On your computer, change the Function Generator output to a bipolar sine wave at 2Hz. Verify that you can see the sine wave on your screen.
  4. Use your multimeter to find and measure the resistance of a 1k resistor (color code: Brown, Black, Red).
  5. Build the following circuit on your breadboard. (image)
    The LED is directional! The long end is the positive end.
    Note the internal connections of the breadboard. Each row is a different wire with 5 access holes. The long columns down the sides of the breadboard are wires used to deliver power when the nScope is plugged in. On the left, the red column is ground (0V), and the blue column is -5V. On the right, the red column is +5V, and the blue column is ground.

Did you get it? Great! Try the next challenge before moving on:

    Edit your circuit so that:

  1. The red LED lights up when the button is pushed
  2. The red LED does not light up when the button is not pushed
  3. A green LED does not light up when the button is pushed
  4. The green LED lights up when the button is not pushed
  5. Use only one button, two LEDs, and as many resistors, diodes, or other components as you like
Need a hint?
Current flows from high potential to low potential. For example, current flows through a resistor from 5V to ground, or from ground to -5V.
Also, LEDs need a minimum amount of voltage across them to be visibly lit.
Can you arrange a way for the green LED to be on with a small voltage, but when the button is pushed the red LED forces the green LED voltage too small?
