What are the 2 main functions in a program?

Setup () Function and Loop () Function

Is used in function declarations.

void

It indicates that the function is expected to return no information to the function from which it was called.

void

Is called when a sketch starts.

Setup () Function

It will only run once, after each power up or reset of the Arduino Board.

Setup () Function

Use it to actively control the Arduino Board.

Loop () Function

It loops consecutively, allowing your program to change and respond.

Loop () Function

This is used to specify the flow of execution in a program.

Control Statements

The types of Control Statements

1. If statement

2. If else statement

3. If else if statement

4. Switch/Case statement

It takes an expression/condition in parenthesis and a statement or block of statements.

If statement

If the expression is true then the statement or block of statements get executed.

If statement

It executes when a expression is false.

If else statement

It is very useful to test various conditions using single if…else if statement.

If else if statement

Controls the flow of programs by allowing the programmers to specify different codes that should be executed in various conditions.

Switch/Case statement

What are the two ways to turn on the Arduino Board?

1. Usb cable (Type B) 5V Only

2. DC Power Jack 7-12V Only

What are the 3 Arduino Uno R3 Board Pins?

1. 14 Digital Pins

2. Power Pins

3. 6 Analog Pins

What does “GND”?

“Ground” pin

Negative terminals

Ground Pins

Positive terminals

Power Pins

Are for digital signals

Digital Pins

Used to read the signals through the serial monitor.

Digital Input

Can be used to light the LED, Motors and etc.

Digital Output

Can be used for input or output

Digital Pins

What does TX stand for?

Transmitter

What does RX stand for?

Receiver

These pins are used in serial communication modules like: Bluetooth

TX and RX Pins

Can be used in uploading a code also.

TX and RX Pins

What does PWM stand for?

Pulse Width Modulated

This can control the brightness of the LED, motor movements.

Analog Output

What can PWM Pins be used for?

Digital Input/Output

Used to read the UPCOMING analog signals and measuring their values. Ex. Sensors, Potentiometers and etc.

Analog Input
