Step $1/5$

Identify the components required: $74$HC$390$ dual decade counter, $7$segment display, resistors, push buttons, logic gates, and voltage source.

Explanation

To design an electric scoreboard that can display a maximum score of $38,$ we need a dual decade counter like the $74$ HC $390$ to count the scores, a $7-$segment display to show the score, resistors to limit current through the display, push buttons to increment the score, logic gates to control the counter, and a voltage source to power the circuit.
