i am doing a project to to recognize the sign language of the dumb people through the flex sensors put on the glove and giving the output of the sensors to the aurdino. i need a program which will recognize the input from the sensors and display the appropriate symbol. pls can any one help me and get me the code. thank you. i have attached a attachment which will explain it in detail.

So you better start writing it or at least start learning how to write code. This is a complex project and it will not be 100% successful.

What you need to do is to record the sensor input and then match what is received to a number of pre recorded templates of single gestures. The match will not be exact but will be wrong to a greater or lesser extent. The least wrong match is what you should choose.

This is simplifying what you need to do, in practice it will be much more complex. I am not sure if the Arduino Uno has enough memory or speed for this, you might have to go with a Due.

Best of luck.

thankx for the suggestions... but can i get some code for the flex sensors so it would be helpful.

A flex sensor is just a variable resistor, so the code is just an analogRead function call. Just the same as if it were a pot.
