Question

Laboratory Exercise # 6 Objective: Portland Community College needs a new bascball scorcboard. The MT122 students were asked to do the logic for the strikes and balls display Circuit Description: The scoreboard will have 2 LED's for strikes, and 3 LED's for balls. The score operator will have 2 switches, onc for strikes, and the other for balls. Each activation of the strike switch will turn on one (more) of the strike lights unless both are already on, If 2 of the red led's are illuminated, and the strikes switch is activated, all LED's including the strikes and the balls are cleared. The balls switch works in a similar manner, If 3 of the green led's areluminated, and the balls switch is activated, all LED's including the strikes and the balls are cleared Procedure Two count sequences are required. Either sequence may be completed first. The sequence completed first must clear both counting devices Consider using in your design the 74175 device as a shift register 2. The counting devices are “clocked" manually. The switches will need to be "debounced (remember thelab The recommended method of doing this is to use a 555 timer connected as a "one shot" as used in Lab 3. 3. Using the IC's indicated, draw a block diagram and then a schematic of the circuit and include them in you report. 4. Build the circuit, test it and demonstrate that it functions properly

does anyone have an idea on how to construct this circuit.? what schematic would work for it?
