So this thing has an ego problem (or maybe its just shy). It looks away each time you get real close to it.

Code:

#define trigPin 10
#define echoPin 11
#include <Servo.h>

Servo myservo;

void setup() {
Serial.begin (9600);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
myservo.attach(9);

randomSeed(analogRead(0));
}

void loop() {
int duration, distance,pos=0,i;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration/2) / 29.1;
Serial.print(distance);
Serial.println(” cm”);
if(distance<15)
{
myservo.write(random(0,180));
//Serial.print(distance);
//Serial.println(” cm”);
}
delay(100);
}

The goal is to make a rain wiper for a glass. Whenever it detects rain, it starts wiping. This project uses water sensor, servo motor and an Arduino. Didn’t find any rubber to imitate the wiper on the windshield on a car, so instead I used a piece of transparent plastic. What to be improved is, the water doesn’t vanish because of the plastic is too loose to touch the glasses surface. This will be improved in next phase.

I saw this after doing the project..:

Servo wiper;
int waterPin = 1;

swipeSlow();
}
else if(waterValue >= 650){
swipeFast();
}
//swipeSlow();
}

void swipeSlow(){

for(pos = 90; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
wiper.write(pos); // tell servo to go to position in variable ‘pos’
delay(10); // waits 15ms for the servo to reach the position
}

for(pos = 0; pos < 90; pos += 1) // goes from 0 degrees to 180 degrees
{ // in steps of 1 degree
wiper.write(pos); // tell servo to go to position in variable ‘pos’
delay(10); // waits 15ms for the servo to reach the position
}
}

void swipeFast(){

for(pos = 90; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
wiper.write(pos); // tell servo to go to position in variable ‘pos’
delay(5); // waits 15ms for the servo to reach the position
}
for(pos = 0; pos < 90; pos += 1) // goes from 0 degrees to 180 degrees
{ // in steps of 1 degree
wiper.write(pos); // tell servo to go to position in variable ‘pos’

My originally idea was to make a eye mask for my trip in airplane or train. When I nearly finished my wife suddenly found it was very suitable for me when I sat on the beach. So it gave me inspiration.

We made the lens as heart shape.  If I laid down the mask would be on. So I could hide myself from the sunshine. If I sat up the mask would be off. So it wouldn’t bother me for enjoying bikini girls ;-D

The code is here,

#include <Servo.h>

Servo myservo;

int switchPin = 3; // tilt sensor input to 3
int val; // the tilt value, 0 or 1

void setup()
{
myservo.attach(9);
pinMode(switchPin, INPUT);
Serial.begin(9600);
}

void loop()
{
val = digitalRead(switchPin);
Serial.println(val);

if (val == 1){
myservo.write(90);
delay(15);
}
if (val == 0){
myservo.write(180);
}
}

I’ve made an indicator which can move when people revolve the knob. And with the movement of the indicator, 2 leds will be turned on. If the indicator moved in 120 degree, the green one will be brighter and brighter, but it will turned off if the indicator moved more than 120 degrees. After the green one turned off, the right one will be on and show the dangerous. I am trying to get some connection between this one with the speed of the car.

// Sweep

// This example code is in the public domain.
#include <Servo.h>
int led1 = 6;
int led2 = 5;
Servo myservo; // create servo object to control a servo
int sensor = A0;// a maximum of eight servo objects can be created
int brightness;
int pos = 0; // variable to store the servo position

void setup()
{
myservo.attach(9);
Serial.begin(9600);
pinMode(sensor, INPUT);
pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT); // attaches the servo on pin 9 to the servo object
}

void loop()
{
pos = map (analogRead(sensor),0,1023,0,180);
myservo.write(pos);
if(pos>=60){
brightness= map(pos,60,180,255,0);
analogWrite(led1, brightness);
analogWrite(led2,LOW);
}else{
brightness= map(pos,0,60,255,0);
analogWrite(led2,brightness);
analogWrite(led1, LOW);
}
Serial.println(pos);
}
