Apply 5B: Use a 7-Segment Decoder to Drive a 7-Segment Display 1. Draw the wiring diagram of the 74LS47 device driving the common-anode 7-segment display through 3300 resistors in series, one per segment. 2. Build the circuit based on the wiring diagram. Tie off any control inputs of the 74LS47 device to enable it as a 7-segment decoder. Test all the segments of the display by temporarily connecting LT (pin 3 of 74LS47) to GND. Then connect D, C, B, and A of the 74LS47 device to power or ground rail and cycle through the 16 combinations to verify that the display shows the characters according to the truth table of the 74LS47 device. 3. Now interface the circuit in Apply 5A.4 with the circuit in Apply 5A.2 such that the display only shows the numbers controlled by N3N₂N₁No that are prime. When the numbers are non-prime, the display should be blank. Hint: use a single device with basic gates.

Design the interface for a positive logic switch to TM4C123GXL Port A pin 7. Show formulas and calculations for each circuit element. Draw the circuit schematics with components labelled with their names and values. Write the C code as a function to initialize the port for interfacing the switch. Write a function to read the data value of Port A pin 7. Comment your code to explain each initialization step clearly.

2. Picture a typical 7-segment LED display (e.g. one digit of a typical digital alarm clock). Your task is to design a combinatorial circuit that controls whether the top-left (LED z_3). LED z_3 is lit for numbers 0, 1, 2, 3, 4, 7, 8 and 9; and blank for all other inputs (including invalid inputs). 2:0123456789 A. Write the truth table for this circuit. (LED z_3 only) B. Express the truth table in Sum-of- Products form. C. Draw the logic diagram for this combinatorial circuit in "PLA-Style". (Hint: Use a ruler or straight edge for wires.)

Build the monostable 555 circuit on TinkerCAD, where the output is an LED.

1.1 Design a circuit for the traffic light unit in Multisim. The design should include 3 positive edge triggered D flip-flops. Set your clock signal to 1Hz. Please include Four screenshots of your working circuit, with each screenshot showing each of the light configurations shown in Figure 1. 000 100 010 110 001 Figure 1. A state diagram for a traffic light control The design should include 3 positive edge triggered D flip-flops. Use 1 flip-flop to control the on and off of a given light, and the state machine should switch from Red (100) -> Red and Amber (110) - > Green (001) -> Amber (010) and repeat the cycle again, with the following transition table: Current state Next state 000 100 100 110 110 001 001 010 010 100 ABC A*B*C* Table 1.
