.Machine Week.

Lets start with the machine week😈

We started by jotting down potential ideas that we could complete in the time span

This was one of the ideas,

A steel wire bender that can be used for Wireframe prototyping

We bounced around a few more ideas such as:

automatic sander

Coke can cannon

pick and place soldering machine

We finally decided to make a onewheel

  
    #include 

#define PIN 6
#define WIDTH 10
#define HEIGHT 10
#define NUMPIXELS (WIDTH * HEIGHT)

Adafruit_NeoPixel matrix(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

byte heat[WIDTH][HEIGHT];

// Zig-zag mapping
int getIndex(int x, int y) {
  if (y % 2 == 0) {
    return y * WIDTH + x;
  } else {
    return y * WIDTH + (WIDTH - 1 - x);
  }
}

// Convert heat to flame color
uint32_t heatColor(byte temperature) {
  byte t = temperature;

  if (t > 170) {
    return matrix.Color(255, 255, t - 170); // yellow-white
  } else if (t > 85) {
    return matrix.Color(255, t - 85, 0); // orange
  } else {
    return matrix.Color(t, 0, 0); // red
  }
}

void setup() {
  matrix.begin();
  randomSeed(analogRead(A0));
}

void loop() {

  // Step 1: cool down
  for (int x = 0; x < WIDTH; x++) {
    for (int y = 0; y < HEIGHT; y++) {
      heat[x][y] = max(0, heat[x][y] - random(0, 40));
    }
  }

  // Step 2: heat rises
  for (int x = 0; x < WIDTH; x++) {
    for (int y = HEIGHT - 1; y >= 2; y--) {
      heat[x][y] = (heat[x][y - 1] + heat[x][y - 2]) / 2;
    }
  }

  // Step 3: new sparks at bottom
  for (int x = 0; x < WIDTH; x++) {
    if (random(100) > 60) {
      heat[x][0] = random(160, 255);
    }
  }

  // Step 4: display
  for (int x = 0; x < WIDTH; x++) {
    for (int y = 0; y < HEIGHT; y++) {
      matrix.setPixelColor(getIndex(x, y), heatColor(heat[x][y]));
    }
  }

  matrix.show();
  delay(50);
}

Simulating servos

Since there is no physics in wokwi to control 3 phase motors, i started experimenting weith servo simulations as well



  #include 

Servo esc;

void setup() {
  esc.attach(9);
  
  // Arm ESC (important in real life)
  esc.writeMicroseconds(1000);
  delay(2000);
}

void loop() {
  // Increase speed
  esc.writeMicroseconds(1200);
  delay(2000);

  esc.writeMicroseconds(1400);
  delay(2000);

  esc.writeMicroseconds(1600);
  delay(2000);

  esc.writeMicroseconds(1000); // stop
  delay(3000);
}

code for controlling the servo
