Electrical Engineering Final Presentation

  1. 1. Electrical Engineering By Kimi Hirano, Kevin Adams, Destiny Alvarado, Camila Alvarez-Buylla and Sethmi Kachchakaduge
  2. 2. Overview ● Specifications of Electrical Engineering ● Microcontroller (Programming) ● Module ● Final Project
  3. 3. Electrical Engineering “The study and application of electricity, electronics, and electromagnetism” - and as a whole, electrical hardware ● Invention of transistor → integrated circuit
  4. 4. Real World Applications ● Microprocessors ● Power systems ● Telecommunication systems
  5. 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. 6. Microcontroller Board
  7. 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. 8. LED Image
  9. 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. 10. 7 segment LED Diagram
  11. 11. Piezoelectric Speaker Able to play sound of a given electrical frequency Coding ● Pause ● Duration ● Frequency
  12. 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. 13. Potentiometer Function Benefits, opposed to average resistor
  14. 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. 15. Materials for Project
  16. 16. Code/Software
  17. 17. Challenges ● Details ● Hardware ● Matching port number ● Troubleshooting
  18. 18. Code
  19. 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.
