File include error while using Arduino Nano I am using the code below to interface the Arduino nano and android cell phone to enable serial communication through the USB port. I downloaded the filter library from GitHub https://github.com/JonHub/Filters

I am getting an error saying thet the library is not found.
I would really appreciate some suggestions on this.

Here is my code:

 //This code is for arduino communicating to android phone through USb serial port.
 //For arduino nano

 #include &lt;Filters.h&gt;   //implements digital filters which mimic the analog filter, keep track of variable statistics in realtime

char data_read; //character datatype takes up to 1 byte of memory
unsigned int analog_out;
unsigned long time;
float filterFrequency = 10.0;
FilterOnePole lowpassFilter( LOWPASS, filterFrequency );//implements digital RC type filter; both highpass and lowpass

 void setup()
 {
  Serial.begin(115200); //open the serial port and set the baud rate for communication
  // create a one pole (RC) lowpass filter

 }
 void loop()
 {
 }

 void serialEvent() { //Used when data is unavailable yet
 if (Serial.available()) //checks the number of bytes available for reading from the serial port
 {
data_read = Serial.read();

if (data_read == '0') {
  Serial.print("#");

  //Serial.print("10100");
  analog_out = lowpassFilter.input( analogRead(0) );
  Serial.print(analog_out + 10000);

  Serial.print(":");

  //Serial.print("20200");
  analog_out = lowpassFilter.input( analogRead(1) );
  Serial.print(analog_out + 20000);

  Serial.print(":");

  //Serial.print("30300");
  analog_out = lowpassFilter.input( analogRead(2) );
  Serial.print(analog_out + 30000);

  Serial.print("p");
}
/*if(data_read == '0' || data_read == '1' || data_read == '2' || data_read == '3' || data_read == '4' || data_read == '5'){
  analog_out = lowpassFilter.input( analogRead( data_read-48 ) );
  Serial.print((analog_out)+(data_read-48)*10000);
  Serial.print(":");
  }else if(data_read =='p'){
  Serial.print("p");
  }*/
   }
 }


Here is my error message:

  This report would have more information with

You have to put the folder with the library files in the folder libraries under your sketchbook folder. Then the IDE should be able to find them.

I think there is also a possibility to save them in the same folder as your .ino file, but it I don't know how exactly you have to do this.
