Final Project
Today, we are going to be talking about the ..,..........,and
the different modules that we created and tested.
Electrical Engineering The study and application of electricity,
electronics, and electromagnetism - and as a whole, electrical
hardwareInvention of transistor integrated circuit
Real World ApplicationsMicroprocessorsPower
systemsTelecommunication systems
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 2Programmed on
Basic Stamp Editor
Microcontroller Board
Microcontroller
2 lead semiconductor light source, emits light when voltage is
appliedUnicolor vs Bicolor

Final Project Combined all the modulesResulted 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.
