This is an illustrative demo story, written to show how builder stories will look on Spark Academy.
Rohan wanted a small robot that could follow a line on the floor. He had a microcontroller, two motors and a lot of questions.
Sensors first
He learned to read a sensor before he tried to drive a motor. Every step was tested separately.
Failing usefully
The first version spun in circles. The fix was a simple feedback loop, the same idea taught in the robotics course.
