Introduction to Arduino - Basics programming
- 1. The Arduino life Workshop on Arduino Embedded Development Board 1
- 2. The heart of engineering isn’t calculation; It’s problem solving. Schools may teach the numbers first, but calculation is neither the front end of engineering note its end goal. Calculation is one means among many to finding a solution that provides useful, objectively measurable improvement. 2

- 5. 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” 5
- 10. 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.” 10

- 24. 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 24
- 25. 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. 25
- 26. 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) 26
