Hi! Can you help me how to program the alphabet letters in American Sign Language using flex? I have already started to code but my problem is letter a and c is the same in recognizing. T_T Please help me 
thankyouuuuuuuuu
int flexPin1 = A0;
int flexPin2 = A1;
int flexPin3 = A2;
int flexPin4 = A3;
int flexPin5 = A4;
int thumb;
int index;
int middle;
int ring;
int pinky;
int thumb1;
int index1;
int middle1;
int ring1;
int pinky1;
//int thumb2;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
pinMode(flexPin1, INPUT);
pinMode(flexPin2, INPUT);
pinMode(flexPin3, INPUT);
pinMode(flexPin4, INPUT);
pinMode(flexPin5, INPUT);
}
void loop() {
// put your main code here, to run repeatedly:
int thumb = analogRead(flexPin1);
int index = analogRead(flexPin2);
int middle = analogRead(flexPin3);
int ring = analogRead(flexPin4);
int pinky = analogRead(flexPin5);
Serial.print("Thumb: ");
Serial.println(thumb);
thumb1 = map(thumb, 62, 220, 0, 100);
thumb1 = constrain(thumb1, 0, 100);
//Serial.print("Thumb Constrain Value: ");
//Serial.println(thumb2);
Serial.print("Thumb Mapped Value: ");
Serial.println(thumb1);
Serial.print("Index: ");
Serial.println(index);
index1 = map(index, 0, 272, 0, 255);
index1 = constrain(index1, 0, 255);
Serial.print("Index Mapped Value: ");
Serial.println(index1);
Serial.print(“Middle:”);
Serial.println(middle);
middle1 = map(middle, 75, 190, 0, 100);
middle1 = constrain(middle1, 0, 100);
Serial.print("Middle Mapped Value: ");
Serial.println(middle1);
Serial.print("Ring: ");
Serial.println(ring);
ring1 = map(ring, 80, 249, 0, 100);
ring1 = constrain(ring1, 0, 100);
Serial.print("Ring Mapped Value: ");
Serial.println(ring1);
Serial.print("Pinky: ");
Serial.println(pinky);
pinky1 = map(pinky, 95, 282, 0, 100);
pinky1 = constrain(pinky1, 0, 100);
Serial.print("Pinky Mapped Value: ");
Serial.println(pinky1);
if (thumb1>=50 && thumb1<=80 && index1==0 && middle1>=0 && middle1<=36 && ring1>=0 && ring1<= 25 && pinky1>=0 && pinky1<= 55)
{ Serial.println(“A”); }
else if (thumb1>=20 && thumb1<=45 && index1>=0 && index1<=220 && middle1>=70 && middle1<=105 && ring1>=80 && ring1<= 105 && pinky1>=0 && pinky1<= 90)
{ Serial.println(“B”); }
