Introduction to Arduino development

• This topic is a very basic introduction to the Arduino

development and the prototype board.

• This is so you can refresh your basic C programming skills.

• In the process you will also become comfortable with the

Arduino prototype board.

• In future classes we will be delving deeper into the architecture

of the ATMega so we can implement and study real time systems.

Arduino

Pins

• This is the prototype board we will be

using in our class.

• Broadly speaking, any embedded

program can:

1.Turn ON/OFF pins.

2.Read data from pins.

Digital I/O

Digital I/O pins

• Input/Output (I/O) is done through pins.

• Input = read physical world data.

• Output = write data to the physical world.

• You insert a wire into a pin and connect it

to something else.

• We can program a pin to be input OR

output.

• Digital pins have two values: high (5 Volts)

or low (0 Volts).
