Multi-Media Logic Worksheet

Create the following devices using Multi-Media Logic. Make sure that each number is saved in a separate file.

1. Create a traffic light using three LED's, two switches, and logic gates. The red LED should turn on when both switches are on; the yellow LED should turn on when one of the switches is turned on; and the green LED should turn on when both switches are turned off. Only one light should be on at one time.
2. Using a four bit counter, two switches, an oscillator, and five LED's create a representation of binary counting. One switch should control whether the counter counts up or down. The other switch should reset the counter. the oscillator controls the speed at which the counter counts. Four LED's represent four binary digits. The final LED represents whether there has been a carry or not. Be sure to set the oscillator slow enough that the counting can be seen.
3. Using the devise from question two, create an eight bit counter by adding LED's and another four bit counter.
4. Using a momentary switch, an ASCII keyboard, and a display create a device that displays the user's typing.
5. On the same page as number four add a second ASCII keyboard and seven LED's to represent the binary equivalent of the typed ASCII character.
