The document provides an overview of an Arduino workshop that covers embedded systems and the Arduino development board. It includes sections on Arduino basics, architecture, components, programming fundamentals, and example projects interfacing LEDs, sensors and actuators. The workshop introduces concepts like open and closed loop control systems. It also explains the Arduino IDE, basic coding structures like setup and loop functions, and how to interface common electronic components like sensors, displays and motors to an Arduino board. Project examples include blinking an LED, controlling an RGB LED using PWM, reading from light and temperature sensors, and controlling motor speed.

- 4. System & Control System / Plant: “A system may be a piece of equipment, perhaps just a set of machine parts functioning together, the purpose of which is to perform a particular operation”. Control System: “A control system is an interconnection of components forming a system configuration that provide a desired system performance” 4

- 9. Embedded Systems "It is a combination of hardware and software to perform a specific task" “An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in common use today.” 9

- 21. setup() function •Called when a sketch starts. •To initialize variables, pin modes, start using libraries, etc. •Will only run once, after each power-up or reset of the Arduino board. loop() function •Loops consecutively. •Code in the loop() section of the sketch is used to actively control the Arduino board. Commenting •Any line that starts with two slashes (//) will not be read by the compiler, so you can write anything you want after it. Basic Coding structure 21
- 22. pinMode() Instruction used to set the mode (INPUT or OUTPUT) in which we are going to use a pin. Eg: pinMode (13, OUTPUT); ie. setting pin13 as output. digitalWrite() •Write a HIGH or a LOW value to a digital pin. •Eg: digitalWrite (11, HIGH); •ie. setting pin 11 to high. 22
- 23. digitalRead() •Reads the value from a specified digital pin, either HIGH or LOW •Eg: int inPin=7; val = digitalRead(inPin); •ie. reads the value from inPin and assigns it to val. delay() •Pauses the program for the amount of time (in milliseconds) specified as parameter. •Eg: delay(1000); •ie. waits for a second (1000 ms = 1 s) 23
