CT 318 Microprocessor Systems This course provides understanding the architecture of microprocessor-based systems: registers, study of microprocessor operation, assembly language, arithmetic operations, and interfacing. INTENDED LEARNING OUTCOMES 1. Explain the principles of LEDs which use in a broad range of LED devices with using digital and analog outputs. 2. Distinguish functions and parameters use in digital and analog outputs. 3. Apply skills in electrical, electronics and programming, to develop various LED devices. At the end of the course, the students are able to: 1. Perform modern electronic systems with microprocessor/microcontroller, digital logic, and digital interfaces. 2. Recognize usefulness of microprocessor/microcontroller platform to develop AI, IoT and Embedded Systems. (PO1, PO6, PO7, PO8) CLO 3. Develop knowledge, skills and techniques necessary in Industry-based professional practice. 4. Apply automation by means of microprocessor/microcontroller platforms.

19. LED USING POTENTIOMETER

20. SOURCE CODE int ledPin = 10;
int readValue = 0;
int ledValue = 0;
void setup() {
// put your setup code here, to run once:
pinMode(ledPin, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
readValue = analogRead(A0);
ledValue = map(readValue, 0, 1024, 0, 225);
analogWrite(ledPin, ledValue);
}

21. THEORY

40. ACTIVITY
ON A ¼ CLEAN YELLOW PAD PAPER, WRITE AND MODIFY THE CODE OF OUR
PREVIOUS ACTIVITY WHICH IS CONNECTING LED ON ARDUINO. THIS TIME
YOU WILL NEED TO USE A GLOBAL VARIABLE. YOU WILL BE GIVEN 10
MINUTES TO WRITE THE CODE.
DON’T FORGET TO WRITE YOUR NAME
AND DATE TODAY!

41. HANDS-ON ACTIVITY
THIS ACTIVITY IS BY PAIR, PERFORM THE SAID ACTIVITY USING ARDUINO UNO
AND ARDUINO IDE BASED ON THE PREVIOUS ACTIVITY WHICH IS CONNECTING
LED WITH THE USE OF A GLOBAL VARIABLE IN THE CODE. YOU WILL BE
GIVEN 10 MINUTES TO WRITE THE CODE.
