Syllabus and Course Outline
Course Topics Civil and Environmental Engineering – Graduate TA’s MATLAB: applications basic engineering analysis to (CLO 1-4) Electrical and Computer Engineering – Dr. John Helferty Arduino microprocessors, servo motor control, sensing using
photoresistors and ultrasonics, and wireless communications. (CLO 1-4)
Mechanical Engineering – Dr. Pillapakkam Solidworks in CAD/CAM software, 3D printing, basics of machining
(CLO 1-4)
Grading Each of the above section in CEE, ECE, and ME will carry a weight of
20% each for a total of 60% Hovercraft Design and final competition 30% Dr. Baren technical communications 10%
Breakout Groups Take 150 students and divide
them into 3 sections. Each section attends one of
the 3 components for 3 weeks. Rotation is done for two cycles,
that is each section will attend each component twice
Last two weeks are completing the hovercraft

ECE COMPONENT The Arduino Processor, Robots
and Gadgets
What is a micro-controller?(The Arduino Uno)
• A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.
• The Arduino Uno is a microcontroller board based on the ATmega328 .
• The Arduino Uno is a special micro controller which has all of its I/O pins mapped out for connecting various kind out of sensors and other I/O pheraphial devices. This I/O pins can be controlled directly by providing programming instruction in the Arduino IDE called a sketch.
How is it Implemented(The connection between the hardware and
software) • All the sensors are connected to the digital I/O
pins of the Arduino Uno Microcontroller .
• Once the Hardware is connected (the sensors and the motors) to the board, the software is written on the Arduino IDE in a file called Sketch. The sketch are similar to C++ programming language, but are linked to various precompiled functions that takes care of lot of behind the scene hardware programming involved .
• Once the desired Sketch is written, the Sketch is uploaded to the flash memory of the Arduino Uno’s flash memory via a USB cable.
How does the Robot work?• The Arduino Uno based robot is based on the concept of digital feedback control network .
• A feedback control network takes in information from the sensors and goes through a algorithmic decision making process, that drives the Robot .
• In this case we use a ping ultrasonic sensor that makes a measurement of distance to the left, right and in front of the robot.
• After making the measurements, the microprocessor compares all the values and makes a decision of going in the direction of the maximum distance.
The ECE Plan: First 2 weeks Week 1: Introduction to the Arduino Integrated
