Section 1 instructed me to construct a push button counter which would increment a counter on a rising edge and display the count on a 7-segment display. The rising edge trigger was achieved using an \textit{AND} gate gate and a D-flop. Since the D-flop goes high on the rising edge, the delay of  the \textit{AND} gate lets the signal go high momentarily before the \textit{NOT} causes it to go low. I then connected the output of the counter to a 7 segment display (not shown).
