Activity 1.2.4 Breadboarding
Description:
Breadboarding is an essential skill for anyone who plans to design analog and/or digital circuits.
In this activity you will gain experience using a breadboard to build and test simple analog circuits. In future activities we will breadboard digital circuits as well.
The circuits analyzed in this activity are some of the same circuits that were analyzed by hand in Activity 1.2.2 and simulated in Activity 1.2.3. This will allow you to compare the theoretical, simulated, and measured values.

Conclusion
1. You have now analyzed the same circuits three times;
a. by hand in Activity 1.2.2
b. via simulation in Activity 1.2.3
c. via breadboarding in this activity
How did these values compare and what might account for any differences?
Some of the values were a little different and some values were very different. This could have been because of human error or simulations and hand calculations aren’t as accurate as doing it with a breadboard.
2. How does the technique for measuring current with a DMM differ from measuring voltage?
Measuring current requires it to be spliced into the circuit, measuring voltage does not.
3. What is the origin of the name “breadboard”?
Breadboard received its name because it is flat and rectangular like a real breadboard which is used to slice or knead bread dough.
