Full Adder

Objective 2-A

Implement a simple microprocessor using digital logic design

Description

A full adder is a digital circuit that performs addition. Full adders are implemented with logic gates in hardware. A full adder adds three one-bit binary numbers, two operands and a carry bit. The adder outputs two numbers, a sum and a carry bit. The term is contrasted with a half adder, which adds two binary digits.

4 bit Adder

Objective 2-B

Implement a simple microprocessor using digital logic design

Description

The 4-bit adder I researched uses a one-half adder and three full adders to compute the two 4-digit binary numbers together and will have a carryout put that is the overflow. Each adder uses two regular inputs, A and B, with the carry from the previous adder as a third input. The 4-bit adder I researched and built computes the two 4-digit binary numbers threw a series of seven XOR gates, seven AND gates, and 3 OR gates resulting in the final output of the two 4- digit binary numbers computed and added together.

555 Timer PCB Board

Objective 3-B

Demonstrate embedded system design skills, including, but not limited to, microcontroller selection, schematic design, printed circuit board layout, design for electromagnetic compatibility and design for manufacturing

Description

This PCB board is for the 555 timer IC. It will flip flop states and blink an LED depending on the size of the capacitors connected to it. It is all done through a series of resistors, transistors, and voltage dividers, inside the IC, that monitor the voltages. Once the voltage drops low enough it flip flops the circuit to the higher voltage till that capasitor discarges then flops back.

Smart Visor

Objective 4-B and Objective 5-A

Obj 4-B: Apply knowledge of transducers, actuators and simultanous hardware and software development in the design of an embedded system

Obj 5-A: Design and anallyze real-time embedded systems, including advanced digital logic design, signal processing and high-speed digital systems

Description

The Smart Visor consists of the current style sun visor in your everyday car. It will have a motor attached to it that is controlled by a microcontroller. It will take inputs from three sensors, a photoresistor, a compass, and a clock. Using these inputs, it will be able to determine the car’s directional heading, combined with the time of day(Sunrise and Sunset) it will lower the visor to protect the driver's eyes from the sunlight. It will also be able to lower the visor if there is only an increase in light levels if it is outside of the sunrise and sunset time frame.

Innovation Claim

This project is innovative because it takes the regular sun visor from a vehicle and turns it into a smart visor by incorporating a microcontroller that uses inputs from three sensors to autonomously adjust the sun visor for the driver. This improves safety by allowing for more hands-free driving and improved visibility for the driver.

Smart CAR with Object Detection

Objective 6-A

Implement and evaluate algorithms and methods enabliing autonomy in a mobile robot

Description

This is a fully autonomous car that uses a Arduino Uno as its brain to control the drive motors and an ultra sonic sensor that allows it to see. Once an object is detected in fornt of its selve it will back up and use a servo to turn the ultra sonic sensor left and right to find a clear path to turn to.
