This document provides an overview of an electrical engineering course that covers microcontrollers, programming, and a final project. It discusses key topics like microcontrollers and how they contain interfaces to connect to users and perform tasks. The modules covered include using LEDs, 7-segment displays, speakers, potentiometers, and servo motors. For the final project, students combined all the modules into a countdown program that used a servo motor, LED, and different beeps to count down and loop four times.

2. Overview
● Specifications of Electrical Engineering
● Microcontroller (Programming)
● Module
● Final Project

3. Electrical Engineering
“The study and application of electricity,
electronics, and electromagnetism” - and as a
whole, electrical hardware
● Invention of transistor → integrated circuit

4. Real World Applications
● Microprocessors
● Power systems
● Telecommunication systems

5. Microcontroller (Programming)
● A microprocessor, memory, and programmable
inputs/outputs.
● Contains interfaces to connect to the user and perform
designated tasks.
● Varies in speed, memory size, port size, etc.
● Hardware from Parallax, Basic Stamp 2
● Programmed on Basic Stamp Editor

6. Microcontroller
Board

7. 2 lead semiconductor light source, emits light when voltage
is applied
● Unicolor vs Bicolor
● Continuous
● Switch Control
● Blinking
o Speed
LED (Light-Emitting Diode)

8. LED Image

9. 7-Segment LED
● Electronic display for displaying decimal numerals
● Functions in counting up/down from 0-9
● Consists of 7 separate LEDs + DP
● Individually programmed

10. 7 segment LED Diagram

11. Piezoelectric Speaker
Able to play sound of a given electrical frequency
Coding
● Pause
● Duration
● Frequency

12. RC Time Constant
● Resistance x Capacitance = Time
● Capacitor
o stores electrical energy (100 nanoFarads)
● Potentiometer
o the variable resistor
● Program displayed
variable time

13. Potentiometer Function
Benefits, opposed to average resistor

14. Servo Motor
Purpose: serves as motor that adjusts angular
position at a predetermined pace
● White = Port (connection to MC)
● Red = Vdd (+)
● Black = Vss (-)
● Programmable

15. Materials for Project

16. Code/Software

17. Challenges
● Details
● Hardware
● Matching port number
● Troubleshooting

18. Code

19. Final Project
● Combined all the modules
● Resulted in countdown from 9 to 0 4 times,
with a beep for each change in number
along with different beep before the start of
each loop while turning the servo motor and
resulting in the LED lighting up.
