I made a drawing machine that is essentially.. basically Microsoft Paint!

Here’s my self portrait:

This actually contains the same information as the following image:

For my self-portrait project, I wanted to make a machine that in a way replicated the shading tool cross-hatching to create new shades and dimension into images. I coded lines that crossed together at various lengths and amounts, then turned these into 4 main drawing tools. You access the erasing shade by pressing ‘c’, the small white shading tool with ‘b’, and the dark cross hatching with ‘v’. Finally, if you press and hold the mouse, you activate the large ‘X’ tool for some interesting shades and patterns. With these four drawing tools, I played around to make the side of a face with new values and seeing how the overlap of these tools combined created new dimension.

 

void setup(){
 size(1000,1000);
 background(225);
}
void draw(){
float x = mouseX;
float y = mouseY;
if (keyPressed){
  if(key =='v' || key == 'V'){
  stroke(0);
  line(x,y,x+30,y-30);
  line(x+10,y,x+40,y-30);
  line(x+20,y,x+50,y-30);
  line(x+30,y,x+60,y-30);
  line(x+5,y-15,x+35,y+5);
  line(x+5,y-25,x+40,y);
  line(x+15,y-25,x+45,y-5);
  line(x+25,y-25,x+50,y-10);
  line(x+35,y-25,x+55,y-15);
  }
}
if(mousePressed == true){
  stroke(0);
  line(x,y,x+60,y-60);
  line(x,y-60,x+60,y);
  }

if(keyPressed){
  if(key == 'b' || key == 'B'){
  stroke(255);
  line(x,y,x+5,y-5);
  line(x,y-5,x+5,y);
  }
}

if(keyPressed){
  if(key == 'c' || key == 'C'){
  stroke(225);
  line(x,y,x+30,y-30);
  line(x+10,y,x+40,y-30);
  line(x+20,y,x+50,y-30);
  line(x+30,y,x+60,y-30);
  line(x+5,y-15,x+35,y+5);
  line(x+5,y-25,x+40,y);
  line(x+15,y-25,x+45,y-5);
  line(x+25,y-25,x+50,y-10);
  line(x+35,y-25,x+55,y-15);
  }
}
}

 

I initially wanted to imitate the graceful movement of a bird’s wings flapping to a certain pattern. However due to my materials and construction efforts, instead I made an extremely aggressive bird, which is fitting as October 31st is approaching anyway.

The setup with the coding is very basic; I simply wrote two loops for two servo motors to move up and down at progressing speeds. It’s slightly slower as the servos move upwards in an attempt to replicate the pattern of bird wings flapping. Then, I attached the cardboard wings and tried creating a stable structure to support these motors. The construction is definitely lacking; tape is far too weak to hold up against the consistently moving motors, which proved rather heavy for the support. If anything, the construction was the most challenging. However, for getting the idea across for the movement, the project was relatively successful. I would like to continue working with servo motors in the future to make more graceful structures; so this will definitely be something I revisit.

 

#include <Servo.h>

Servo servo;
Servo servo2;
int position = 0;

void setup() {
  // put your setup code here, to run once:
servo.attach(9);
servo2.attach(10);
}

void loop() {
  // put your main code here, to run repeatedly:
for (position = 0; position <=180; position +=1){
   servo2.write(position);
  delay(2);
}

for(position = 180; position>=0; position -=1){
  servo2.write(position);
  delay(1);
}
 
for (position = 0; position <=180; position +=1){
   servo.write(position);
  delay(2);
}

for(position = 180; position>=0; position -=1){
  servo.write(position);
  delay(1);
}

}
