LineFollower By NIXA

1. Assembling the Chassis

We highly recomend to follow the steps presented on the video included with the project:
https://www.youtube.com/watch?v=qUL7R_-NxVQ

Firmware and complete information you can download from:
https://drive.google.com/open?id=0B72EA_WY7qIta3lDRFM2LUJtblE


2. Flashing firmware
-Download Arduino IDE from https://www.arduino.cc/en/Main/Software. We recomend one of the previous releases i.e. 1.0.6.
-Install IDE
-Project package includes QTR-xRC sensor library, but if you want the lateset release follow next two steps.
-(*)Download QTR-RC3 library form https://github.com/pololu/qtr-sensors-arduino („Download ZIP” button)
-(*)Decompress archive.
-drag the “QTRSensors” folder to your Arduino/libraries directory (usually : C:\Users\i.e. John\Documents\Arduino\libraries)
-Open the Arduino sketch „LineFollower” downloaded from the Zortrax Library .
-Use sensor library by selecting Sketch > Import Library > QTRSensors.
-Compile the sketch.
-Plug in your Arduino Uno to the computer and flash the sketch.


3. Using robot

To provide correct operating of the toy, use standard, black, 19mm insulation tape as a track. Place the tape on the plain, clean surface. Remember that track shouldn't contain any curves with radius smaller than 20cm.
It is necessary to calibrate sensor befor the ride. To do this procedure , please pass sensor over the black line from side to side for 5-10 seconds (until you see that servos started rotating).
