P1-P3P4-P6P7-P9
You can use the standard 'Serial.print' and 'Serial.read' commands to send and
receive serial data. Here's an example that builds on the previous code, adding serial
communication:
intledPin=13;
intbuttonPin=2;
intbuttonState=LOW;
intoldButtonState=HIGH;
charserInput;
voidsetup()
{
pinMode(ledPin,OUTPUT);
pinMode(buttonPin,INPUT);
digitalWrite(ledPin,HIGH);
Serial.begin(115200);
}
voidloop()
{
buttonState=digitalRead(buttonPin);
if(Serial.available()>0)
{
serInput=Ser ial.read();
Serial.println("Miny,Moe.");
}
if(butto
nState!=oldButtonState)
{
if(buttonState==HIGH)
{
digitalWrite(ledPin,HIGH);
Serial.print("Meeny,");
}
else
{
digitalWrite(ledPin,LOW);
Serial.print("Eeny,");
}
}
oldButtonState= buttonState;
}
This example will actually work with both the standard USB serial connection, or a
BlueSMiRF. Give it a try! Note that the baud rate is set to 115200 bps, this is the
default baud rate of the BlueSMiRF. Pressing the button will turn the LED off and
send "Eeny, " out the serial port. Releasing the button will turn the LED back on and
print "Meeny, ". Sending any character to the Arduino, over a serial connection, will
print "Miny, Moe.".
If you want to communicate between your computer and the BlueSMiRF, you will
need a bluetooth dongle of some sort. Many options exist to add bluetooth to your
computer (if it doesn't already have it). For beginners, I'd recommend the Bluetooth
USB module; another, more advanced, option is the USB BlueDongle.
How have others used the shield?
The ProtoShield can be used to prototype just about any Arduino project you could
imagine. As examples of the huge variety of projects the shield has been used for,
check out these links:
• Arduino USB Host
• Ultrasonic Range Finder Tape measure
• Joystick Control of Servo Motors
•4-Bit Maze
• Temperature Monitor/Controller
• Weather Station Receiver
• Basic 555 Timer
