I was trying to figure out the math to make part of the graph show up as brown—i.e., earth—and then scatter flowers on top, but something wasn’t working out and I was running late, so I gave up.
Anyway, here are the progress shots:
I also shot a fascinating movie of the program loading on the Arduino and starting up—you know, flickering yellow light, then blinking LED; hot stuff:
Final code on Arduino:
int potPin = 0;
int potValue = 0;
int ledPin = 2;void setup()
{
// flash LED three times to announce start of program
pinMode( 2, OUTPUT );
digitalWrite( 2, LOW );
delay( 500 );
digitalWrite( 2, HIGH );
delay( 500 );
digitalWrite( 2, LOW );
delay( 500 );
digitalWrite( 2, HIGH );
delay( 500 );
digitalWrite( 2, LOW );
delay( 500 );
digitalWrite( 2, HIGH );
delay( 500 );
digitalWrite( 2, LOW );
delay( 500 );
digitalWrite( 2, HIGH );// start serial port at 9600 bps:
Serial.begin( 9600 );
}void loop()
{
// read analog input, divide by 4 to fit it in the range 0-255:
potValue = analogRead( potPin );
potValue = potValue / 4;
Serial.print( potValue, BYTE );
// pause for 10 milliseconds:
delay( 10 );
}
