yesss, getsture recognization is done, here is my code for that.
but i have no idea for the code to wriitten to connect to that particular app.
i needed help in that guys.
here is my code
include <LiquidCrystal.h>
#include <SoftwareSerial.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
SoftwareSerial BTserial(10,9);
int flexPin1 = A0;
int flexPin2=A1;
int flexPin3=A2;
int value1;
int value2;
int value3;
void setup() {
// put your setup code here, to run once:
lcd.begin(16, 2);
lcd.setCursor(0, 0);
lcd.print("Sign Language");
Serial.begin(9600);
BTserial.begin(9600);
delay(200);
}
void loop() {
// put your main code here, to run repeatedly:
value1 = analogRead(flexPin1);
Serial.print(value1);
if (value1 < 150)
{
lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 0);
lcd.print("Foods");
digitalWrite(6, HIGH);
Serial.println(" Foods");
delay(20);
}
else
{
lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 0);
lcd.print("Sign Language");
lcd.clear();
digitalWrite(6, LOW);
Serial.println(" Sign Language");
delay(500);
}
value2 = analogRead(flexPin2);
Serial.print(value2);
if (value2 < 150)
{
lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 0);
lcd.print("Foods");
digitalWrite(6, HIGH);
Serial.println(" water");
delay(20);
}
else
{
lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 0);
lcd.print("Sign Language");
lcd.clear();
digitalWrite(6, LOW);
Serial.println(" Sign Language");
delay(500);
}
value3 = analogRead(flexPin3);
Serial.print(value1);
if (value3 < 150)
{
lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 0);
lcd.print("Foods");
digitalWrite(6, HIGH);
Serial.println(" go");
delay(500);
}
else
{
lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 0);
lcd.print("Sign Language");
lcd.clear();
digitalWrite(6, LOW);
Serial.println(" Sign Language");
delay(500);
}
if(value1 <80 && value2 <80 && value3 >150)
{ lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 0);
lcd.print("Foods");
digitalWrite(6, HIGH);
Serial.println(" come");
delay(50);
}
if(value1 <80 && value2 >150 && value3 <80)
{ lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 0);
lcd.print("Foods");
digitalWrite(6, HIGH);
Serial.println(" hhee");
delay(50);
}
if(value1 >150 && value2 <80 && value3 <80)
{ lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 0);
lcd.print("Foods");
digitalWrite(6, HIGH);
Serial.println(" call me");
delay(50);
}
