9. E-Textiles and Wearables II#

In the Lecture taken by Liza is very useful to me to understand electronics. I got ineterest to this week as compare to E textile 1. Suhas teached me programming On Arduino IDE software. Dance performance in this video inspire me . This is video of event by rahaniyat in Pune,Maharashtra.

What’s an arduino?#

Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s intended for anyone making interactive projects. Arduino consists of both a physical programmable circuit board and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board. This help me to learn more about Arduino.

What is sensor?#

Sensors are used to measure physical quantities such as temperature, light, pressure, sound, and humidity. They send signals to the processor. To learn more about sensor go here

Wearable E-textile with Ultrasonic sensor#

I am very begining for coding and programming. Suhas help me to understanding ardiuno. I never done anything in electronics before this but suhas and supriya help me amd teach me programming very well. I wanted to make T-shirt with Ultra sonic sensor. For this i used Arduino uno. I desolder Arduino headers to sew it on T-shirt. But It is new for me. I failed to desolder it. Then I use Arduino Nano which is very easy to sewable on fabric. For Arduino nano I changed tools setting in programming. First I draw curcuit on paper then sew it . I create Embroidery of two birds on USHA memory craft 200E machine.

However, I had…

Tools:

Soldering station
Soldering iron
Scissors
Multimeter
Needle

Components:

Conductive thread
Arduino nano
LED
Buzzer
Ultrasonic sensor
Battery 5v
Fabric

Process:

Emroidery On Fabric and make holes where I show LED and Buzzer.
Sew LED and Buzzer on fabric with possitive and negetive sides seprately with conductive tread.
Sew Arduino nano and Ultra sonic as I draw on paper.
Solder the copper tape circuit where is necessary
Use the multimeter to check electrical continuity along the process.
Just after that, Connect all pins and give battery supply.
Finally, I checked it was working as I expected.

I did embroidery of birds on Usha Memory Craft 200E CNC machine.

And make a hole to eyes of those birds for led and make hole and make another hole to bird’s beak where I put buzzer.

I sew all circuit with conductive thread and solder remaining with copper wire.

Code for Ultra sonic senser with buzzer and LED#

// defines pins numbers
const int trigPin = 12;
const int echoPin = 10;
const int buzzer = 6;
const int ledPin = 8;

// defines variables
long duration;
int distance;
int safetyDistance;


void setup() {
pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output
pinMode(echoPin, INPUT); // Sets the echoPin as an Input
pinMode(buzzer, OUTPUT);
pinMode(ledPin, OUTPUT);
Serial.begin(9600); // Starts the serial communication
}


void loop() {
// Clears the trigPin
digitalWrite(trigPin, LOW);
delayMicroseconds(2);

// Sets the trigPin on HIGH state for 10 micro seconds
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);

// Reads the echoPin, returns the sound wave travel time in microseconds
duration = pulseIn(echoPin, HIGH);

// Calculating the distance
distance= duration*0.034/2;

safetyDistance = distance;
if (safetyDistance <= 30){
  digitalWrite(buzzer, HIGH);
  digitalWrite(ledPin, HIGH);
}
else{
  digitalWrite(buzzer, LOW);
  digitalWrite(ledPin, LOW);
}

Learn Attiny microcontroller#

Arduino is awesome. The ATTINY45 is a high performance and low power AVR 8-bit microcontroller with 4K bytes of in-system programmable flash, alongside 256 bytes of EEPROM and 256 bytes of SRAM. It is very useful in e-wearable. I learn Attiny programs. in this assignment I learn only how to program Attiny.

Pinout and configuration of Attiny45

To program the ATtiny85 we need to first set Arduino Uno in ISP mode. Connect your Arduino Uno to the PC. Open Arduino IDE and open the ArduinoISP example file (File -> Examples -> ArduinoISP) and upload it.

Add ATtiny45 Support to Arduino IDE

Open File -> Preferences and in the Additional Boards Manager URLs give this url

After this is done open Tools -> Board -> Board Manager. Open Board Manager scroll down the list where it says “attiny by Davis A. Mellis”. Click on that and install it. After installing this I can see Attiny in board menu.
