Oh, great idea! And it also can be useful for us electronic makers.  
Let’s do it together!  
Here’s my first contribution. A list with the most common resistor values.  
Can you draw the resistor with colored rings as natural-looking as possible?

```auto
String[] resistor_values = {
  "1.0", "1.1", "1.2", "1.3", "1.5", "1.6", "1.8", "2.0", "2.2", "2.4", "2.7", "3.0", "3.3", "3.6", " 3.9", "4.3", "4.7", "5.1", "5.6", "6.2", "6.8", "7.5", "8.2", "9.1", 
  "10", "11", "12", "13", "15", "16", "18", "20", "22", "24", "27", "30", "33", "36", "39", "43", "47", "51", "56", "62", "68", "75", "82", "91", 
  "100", "110", "120", "130", "150", "160", "180", "200", "220", "240", "270", "300", "330", "360", "390", "430", "470", "510", "560", "620", "680", "750", "820", "910", 
  "1.0K", "1.1K", "1.2K", "1.3K", "1.5K", "1.6K", "1.8K", "2.0K", "2.2K", "2.4K", "2.7K", "3.0K", "3.3K", "3.6K", " 3.9K", "4.3K", "4.7K", "5.1K", "5.6K", "6.2K", "6.8K", "7.5K", "8.2K", "9.1K", 
  "10K", "11K", "12K", "13K", "15K", "16K", "18K", "20K", "22K", "24K", "27K", "30K", "33K", "36K", "39K", "43K", "47K", "51K", "56K", "62K", "68K", "75K", "82K", "91K", 
  "100K", "110K", "120K", "130K", "150K", "160K", "180K", "200K", "220K", "240K", "270K", "300K", "330K", "360K", "390K", "430K", "470K", "510K", "560K", "620K", "680K", "750K", "820K", "910K", 
  "1.0M", "1.1M", "1.2M", "1.3M", "1.5M", "1.6M", "1.8M", "2.0M", "2.2M", "2.4M", "2.7M", "3.0M", "3.3M", "3.6M", " 3.9M", "4.3M", "4.7M", "5.1M", "5.6M", "6.2M", "6.8M", "7.5M", "8.2M", "9.1M"
}; 

float loc;
int index;

void setup() {
  size(600, 300);
  println(resistor_values.length);
  loc = 15;
  textSize(28);
  textAlign(CENTER);
  drawSlider();
}

void draw() {
  background(255); 
  fill(0);
  text(resistor_values[index]+" Ω", width/2, 3*height/4);
  drawSlider();
}

void drawSlider() {
  push();
  noStroke();
  index = int(map(loc, 15, width-15, 0, 167));
  fill(255);
  rect(0, height-30, width, 30); 
  fill(200, 200, 255);
  rect(10, height-15, width-20, 5); 
  fill(150, 150, 255);
  ellipse(loc, height-13, 15, 15);
  pop();
}    

void mouseDragged() {
  loc = mouseX;
  if (loc < 15) loc = 15;
  if (loc > width-15) loc = width-15;
}

```

hi plz could u comment the code so I can understand the process
