What’s For Today

• Controlling Arduino from a computer

• Controlling a computer from Arduino

• R,G,B LED color mixing

Remove ProtoShield

First half of class, we don’t need it

And we want to observe the Arduino board

“Shields down, cap’n!”

Recap: Programming

Edit

Compile

Reset

Upload

Remember: always start from a known working system

Communicating

with Others

• Arduino can use same USB cable for

programming and to talk with computers

• Talking to other devices uses the “ Serial ”

commands

• Serial.begin() – prepare to use serial

• Serial.print() – send data to computer

• Serial.read() – read data from computer

Can talk to not just computers.

Most things more complex than simple sensors/actuators speak serial.
