Geared toward more experienced coders, the line-following challenge tests your hardware skills while teaching you how to augment Dash with additional physical sensors as well as Python code.

Create a custom hardware accessory for Dash that enables Dash to reliably follow a line on the ground. We provide a track that can be printed on a standard household printer, a list of suggested hardware item to purchase from Adafruit, and a series of guides created by the Wonder Workshop engineering team.

Line following is a classical problem in robotics, and can be successfully implemented in many different ways. As such, it's a great challenge for robotics enthusiasts of all ages and experience levels. Line-following competitions are even part of university-level robotics programs, as seen in the video below.
