ARDUINO(Shape Memory Alloy)

What is SMA?

Shape Memory AlloyMuscle Wire

A shape-memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that "remembers" its original shape and that when deformed returns to its pre-deformed shape when heated.

Let your SMA

MOVE?

Let’s do the wiring first

On/Off

start with 9V first

Where is the code?

/* Blink Turns on an LED on for one second, then off for one second, repeatedly. This example code is in the public domain. */ // Pin 13 has an LED connected on most Arduino boards.// give it a name:

int led = 9;

// the setup routine runs once when you press reset:void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); }

// the loop routine runs over and over again forever:void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)

delay(3000); // wait for a second digitalWrite(led, LOW); // turn the LED off by making the voltage LOW

delay(3000); // wait for a second}

Change it to 9, otherwise you will burn it

Change the time longer

Basically, the same code as: Ardiuno/Example/Basic/Blink

On/Off

Let’s add stuffs for the wiring

This is what we need to add

So we can more or less control the degrees of it

#include <Servo.h> Servo myservo; // create servo object to control a servo // a maximum of eight servo objects can be created int inPin = 0; int pos = 0; // variable to store the servo position int newPos; //position for remap void setup() {

myservo.attach( 9 ); // attaches the servo on pin 9 to the servo object } void loop() { pos = analogRead(inPin); newPos = map(pos,0,1023,0,179); myservo.write(newPos); delay(15);}

Read the data from “A0”Remap the data from 0-180
