This is just a practice machine for the FSM test and sequential logic

Group C EE-184 Project 3. This circuit is a state machine built-in hardware used to control a stepper motor by interfacing with a motor driver. The inputs are Run, Handwave, and Free Range. In Free Range mode the motor will spin in one direction constantly. When switched to Hand wave mode the motor will move 36 steps clockwise and then 36 steps back counterclockwise. Run must be active to enter either of these states. If Run is deactivated while Handwave is active the motor will finish its 36 step cycle and stop.

Moore and Mealy machines detection the binary sequence 01.

Encoding states: one-hot.

The washing machine will have two states: washing which required a counter that will stop when it reaches number 6 and drying which required a counter that will stop when it reaches number 4. The controller should have 2 inputs a start and a reset. When the start input is disabled (set to 0), both washer and dryer should stop. When the start input is enabled (set to 1), the washing cycle should start counting from 0 to 6 then stop; after that the dryer cycle should start counting from 0 to 4, i.e., the drying cycle will start after the washing cycle finish. The reset button we reset both counters. The final circuit will look something like this

FSM 4 stati con flip flop D

Implementation of a FSM for a vending machine with the following specifications:
• The machine takes nickels and dimes.
• There is a single coin slot, and a sensor detects the type of coin then asserts one of two signals, N for nickel, and D for dime.
• The machine dispenses candy once it receives 25 cents.
• The machine will not return change.

Includes the following I/Os:
a. Two inputs N and D to the circuit
b. A reset input connected to the asynchronous clear
c. A seven segment display which shows the current number of coins (button presses)
d. A single LED as output to indicate when the “vend” condition is true.
