Linefollower Arduino


I’m doing a small project “line follower car” but i am facing some problems with the execution.

These parts are being used :

QTR 8RC sensor array (6 sensors I use)

Arduino Leonardo

HC-05 for Bluetooth communication and changing parameters

DRV 8835 Arduino shield

5v regulator

2 lipo batteries


Goal ;

push on button, batteries power the arduino, arduino reads the values of the sensor. Using mapped values/normalized/.. a position is derived. Then the motors start doing there things if we give the start command via the Bluetooth module.

I have :

already wired the sensor, drv8835 and the 5v regulator.

The HC05 is also easy to wire so this should give no problem.

I also already have a big piece off code for calibrating values and mapping them. Also to get the motors to work but here is the problem. I want this to be fixed.

Clearly read this project before giving an answer.

I only want someone that is capable of doing this in a short amount of time.

Because I have others projects too after this.
