Breadboard Setup and Testing for micro:bit

Review and Practice

Self-check

In this tutorial, you set up a circuit prototyping system.

  • Do you know how to locate a socket on the breadboard by its row number and column letter?
  • Do you know which sockets connect to power and which ones connect to ground?
  • For any given socket, do you know which other sockets it is connected to?
  • Do you know where to plug in two wires so they are connected to each other?

Exercises

For the following exercises, download and print the attached PDF or a larger version of the image below to circle and label sockets.  If possible, test for continuity on your actual board.

Breadboard Setup & Testing Practice and Answers (.pdf)

  1. Pick two sockets in the same row-of-five on one of the terminal strips.  Circle them and label them ‘SR5’ in the drawing.
    • Should they be connected?
    • Test for continuity
  2. On one of the terminal strips, pick two sockets in the same row-of-ten, but on opposite sides of the valley in the middle of one of the terminal strips.  Label the sockets ‘OSV’.
    • Should they be connected?
    • Test for continuity
  3. Repeat the previous setup, but with different rows, and this time, plug in a jumper wire to connect the two rows.  Label the sockets ‘JOSV’.
    • Should they be connected?
    • Test for continuity
  4. In one of the bus strips, circle a socket in the (+) column and one in the (-) column, and label them PM.  
    • Should they be connected?
    • Test for continuity
  5. Circle a socket in the (-) column of one bus strip, and another in another bus strip’s (-) column.  Then, connect the two columns with a jumper wire.  Label them NDCC.
    • Should they be connected?
    • Test for continuity
