This is the project that you have to make the Tinybit follow the lines by coding the Tinybit using the Maccode application from Microsoft with drg & drop coding or you can choose the harder one by using Phython or Java Script. 

This project uses Infrared sencor. It will always move forward until one of the Infrared sensor detect a color Black and the other does not. If the right Infrared sensor detected a color Black and the left Infrared does not will move Right. Else if the right Infrared sencor didn’t detect a Black color but left sensor detected it. It will move left.
