Turn Signal LED Jeans Jacket Ideal for Bikers

For safety purposes, we decided to design a jacket with turn signals that will let people know where you're headed. This is a jacket suitable for cyclers, motorbikers, runners, road emergencies and any situation where visibility is paramount. The integrated LEDs in the back of the jacket can help you be visible in poor light conditions and shows your directions to other road users. Safety is paramount, but design is very important too. The vest has been designed by two students from the high school institution Pulhof, who focused on making this clothing practical but fashionable at the same time. When the vest is switched off, the technology elegantly disappears and you can use it for daily use outside.

• Nano Arduino USB Main Board
• LilyPad LED Lights (25x)
• LilyPad Push Button Board Switches (2x)
• LilyPad Power Supply (LilyPad Coin Cell Battery Holder 20mm Sparkfun 13883)
• A Coin Battery 3V
• Mini USB Cable
• Conductive Thread
• A Digital Multimeter with a Beeping Continuity Tester
• A Pair of Scissors
• A Needle for Sewing
• A Jacket not necessarily a Leather Jacket

Make a clear Design of your Layout. This way you have a clear overview of your plan and it prevents you from making mistakes.

Make sure your thread does not touch each other. You can tape the thread so they're isolated. Test the left side first and see if you undergo any problems. You must surely check them separately to see if you've made any specific errors. Afterward, you can test the right side and lastly, if both sides are working, you can test them simultaneously.

TIP: you can use chalk to outline your desired layout, this makes it easier to sew in the LED sequins. It gives you a clear overview when sewing and you'll prevent any mistakes.

TIP: Make sure you see a clear overview of the (+) and (-) to prevent them from touching each other

TIP: The (+) and (-) threads cannot touch each other !!! You can connect the (-) with each other but the (+) not.

We used a pocket of the jacket to sew in the nano board, this makes it easy to access when problems occur and it will not be visible to the public eye.

This is the code we used, you can copy-paste it and insert it into your nano board.

const int rightbuttonPin = 12;   

const int rightledPin = 11;   

int rightbuttonState = 0;     

const int leftbuttonPin = 10;

const int leftledPin = 9;

int leftbuttonState = 0;

void setup() {

 pinMode(rightledPin, OUTPUT);

 pinMode(rightbuttonPin,INPUT_PULLUP);

 digitalWrite (rightledPin, LOW);

 digitalWrite (rightbuttonPin, HIGH);

 pinMode(leftledPin, OUTPUT);

 pinMode(leftbuttonPin,INPUT_PULLUP);

 digitalWrite (leftledPin, LOW);

 digitalWrite (leftbuttonPin, HIGH);

}

void loop() {

 rightbuttonState = digitalRead(rightbuttonPin);

 if (rightbuttonState == LOW) {

  // turn LED on:

  digitalWrite(rightledPin, HIGH);

  delay (500);

  digitalWrite(rightledPin, LOW);

  delay (500);

 } 

 else {

  // turn LED off:

  digitalWrite(rightledPin, LOW);

 }

  leftbuttonState = digitalRead(leftbuttonPin);

 if (leftbuttonState == LOW) {

  // turn LED on:

  digitalWrite(leftledPin, HIGH);

  delay (500);

  digitalWrite(leftledPin, LOW);

  delay (500);

 } 

 else {

  // turn LED off:

  digitalWrite(leftledPin, LOW);

 }

}
