Robot Single Cell Life Form (Initial Blinky)

I am making a robot that basically performs the same functions of a single cell life form. From that starting point I hope to build upon it and make it more and more complex in terms of its functionality and design. The image shown in Figure 1 is shows the output of the micro-view view controller I am using for this project. The current code on the device just blinks a circle on the screen every second.

#include <MicroView.h>
/*
	MicroView Blink
	Draw a circle for one second, then off for one second, repeatedly.
 
	This example code is in the public domain.
 */
 
// the setup routine runs once when you press reset:
void setup() {                
	uView.begin();
	uView.clear(PAGE);
}

// the loop routine runs over and over again forever:
void loop() {
	uView.circleFill(32,24,10,WHITE,NORM);
	uView.display();
	delay(1000);               // wait for a second

	uView.circleFill(32,24,10,BLACK,NORM);  
	uView.display();
	delay(1000);               // wait for a second
}

The next step is to flash an external led. This was done by connecting an LED to pin 4 and updating the code to set the pin high and low every second, shown in Figure 2.

#include <MicroView.h>
/*
	MicroView Blink
	Draw a circle for one second, then off for one second, repeatedly.
  Also flash an LED connected to pin A3 at the same time.
 
	This example code is in the public domain.
 */

int LED = A3;        // declare LED as pin A3 of MicroView

 
// the setup routine runs once when you press reset:
void setup() {                
	uView.begin();
	uView.clear(PAGE);
  pinMode(LED, OUTPUT);  // set LED pin as OUTPUT
}

// the loop routine runs over and over again forever:
void loop() {
	uView.circleFill(32,24,10,WHITE,NORM);
	uView.display();
  digitalWrite(LED, HIGH);  // set LED pin HIGH voltage, LED will be on
	delay(1000);               // wait for a second

	uView.circleFill(32,24,10,BLACK,NORM);  
	uView.display();
  digitalWrite(LED, LOW);    // set LED pin LOW voltage, LED will be off
	delay(1000);               // wait for a second
}
