Finial Project introduction

I had changed finial project twice for a more funny project
My Evaluate project is Sugar Timer.

Sugar Timeris design for children ,adult can also use it, like me
I want make something can encourage me to work hard and study hard.
so I try to make a counter which can supervise you studying and working.
After you work for a while ,you will get a candy as a reward

I also do some research about it
I use the Validationboard,and I think it’s useful.
SugarTimer.001

Then,I draw some sketch
SugarTimer.002
SugarTimer.003

The Plan

June 5~6th - Electronic design
June 7~10th - Electronic test and programm
June 11~18th - Struct design and test
June 19~20 - Assembling
June 20th - Finial testing and debugging
June 21th - Slide & video

Electronic design

Draw the Schematic

Layout the PCB Board

Output to Roland machine and mill the board

Soldering the board and connect with wire

Electronic test and programm

1
#include <Servo.h>
#include <Ultrasonic.h>
#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
  #include <avr/power.h>
#endif

//==============NeoPixels=============
// Which pin on the Arduino is connected to the NeoPixels?
// On a Trinket or Gemma we suggest changing this to 1
#define PIN            6

// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS      24

#define BRIGHTNESS 5

// When we setup the NeoPixel library, we tell it how many pixels, and which pin to use to send signals.
// Note that for older NeoPixel strips you might need to change the third parameter--see the strandtest
// example for more information on possible values.
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

int delayval = 500; // delay for half a second

int ledPoint = 0;



//===========================


Servo myservo;  // create servo object to control a servo
// twelve servo objects can be created on most boards
int pos = 0;    // variable to store the servo position

Ultrasonic ultrasonic(9,8); // (Trig PIN,Echo PIN)
int distance;

void setup() {
  myservo.attach(10);  // attaches the servo on pin 9 to the servo object
  Serial.begin(9600);

  pixels.begin(); // This initializes the NeoPixel library.
  pixels.setBrightness(BRIGHTNESS);
  pinMode(13,OUTPUT);
}

void loop() {
  distance = ultrasonic.Ranging(CM);
  Serial.print(distance); // CM or INC
  Serial.println(" cm" );
  if(distance<50){
    distance = ultrasonic.Ranging(CM);
    if(distance<50){
      if(ledPoint<=24){
        ledPoint++;
        pixels.setPixelColor(ledPoint,255, 255, 255);
      }else{
        ledPoint = 0;
        sweepOut();
        pixels.clear();
      }
    }
  }else{
    if(ledPoint>0){
      pixels.setPixelColor(ledPoint,0, 0, 0);
      ledPoint--;
    }else{
      ledPoint = -1;
      pixels.clear();
    }
  }
  Serial.print("LedPoint: ");
  Serial.println(ledPoint);
  pixels.show();
  delay(50);
}

void sweepOut(){
  digitalWrite(13,HIGH);
  myservo.write(30);
  delay(500);
  myservo.write(180);
  delay(1000);
  digitalWrite(13,LOW);


}

//no use now
// Fill the dots one after the other with a color
void colorWipe(uint32_t c, uint8_t wait) {
  for(uint16_t i=0; i<pixels.numPixels(); i++) {
    pixels.setPixelColor(i, c);
    pixels.show();
    delay(wait);
  }
}

Struct design and test

Summarise

Before I join the fabacademy,I just know how to programm and design PCB board.
But now, I can design 2D and 3D files,and make it real,but there is still a long way for me to make almost anything.
