Flip-flop is an edge-triggered memory circuit. In this project, we will implement a flip-flop behaviorally using Verilog, and use a bunch of flip-flops to implement a clock divider that blinks the LEDs.

Counting Binary with Six LEDs

This project is very similar to the project “Marching” LEDS. However, we will use the six LEDs to output a six bit binary number instead of “Marching.”

In this project, a button is again used to control an on-board LED, but things get a bit more complicated. Instead of simply having the state of the LED correspond to the state of the button, in this project the LED's state will toggle every time the button is pushed.

Design Challenge 1

In this challenge you will be asked to use push buttons to control the seven segment display on your FPGA board. Each digit of the seven segment display is composed of 7 LEDs arranged in a "figure 8" pattern with another LED for the decimal point. When the buttons are not pressed, all LEDs should be on. When a button is pressed, a digit should turn off.

Resistors in electrical circuits are commonly used to provide other components in the circuit with the voltages and currents they require in order to function properly. For example, in this exercise, we will design our circuit (i.e. choose a resistance value) to ensure that an LED receives the voltage necessary for it to light up without allowing excessive current, which could burn out the LED.
