Intro to AOI Combinational Logic - Activity 1.2.1
Today we will begin Combinational Logic and Truth Tables. Take some basic notes while watching the video What types logic(s) were used when you built your Random Number Generator. |

Analog and Digital Signals - Activity 1.2.2
While watching this video write down the key differences between Analog and Digital Signals. What is the one thing that Analog Signals can do the Digital Signals can not do? Optional: To see a visual difference between analog and digital signals, look at a digital analog TV signal comparison |

555 Timer Traffic Light - Challenge
Watch the circuit operate. - Note how the circuit was modified to have the yellow LED on for less time than the green or red LEDs. - Two 555 timers are being used, are they both being used to create clock signals, or are they using other functions of the 555 IC chips? - This only works as a single traffic light. What type of combinational logic would you add to have this work as a 4 way traffic light? |

Combinational vs Sequential Logic
A lot of information is covered quickly, but take a couple of notes on what the differences are between combinational and sequential logic are. What are examples of the use of each architecture? |
