Real-Time Plotting; Arduino Code

Finally got all the python code worked out for this mini-project; here's what's driving the board:

/*
* data-logging-proto.sch
* +3.3V -> LDR -> A0 -> 10k R -> GND
*/
void setup(){
  Serial.begin(9600);
}

void loop(){
  if(Serial.available() >0){
    int value = analogRead(A0);
    Serial.println(value);
    delay(125);
  }
}

Serial interface Test Code

Here's the source code I used to test out my serial interface programs:

int LED_Pin = 13;

// Hello World for use with serial comms testing.

void setup(){
 Serial.begin(9600);
}

void loop(){ 
  Serial.print("Hello World\n");
 delay(1000);
  Serial.print("Goodbye World\n");
  delay(1000);  
}

LED Test

int LED_Pin = 13;

void setup(){
   pinMode (LED_Pin, OUTPUT);
}

void loop(){
   digitalWrite(LED_Pin, HIGH);
   delay(1000);
   digitalWrite(LED_Pin, LOW);
   delay(1000);
}
