Why doesn’t the Line-following Sensor work?
Please:
1. Make sure the distance between Line-following sensor and line-following map is between 1-2cm, this is the best working range.

Why cannot the software read the value of sensor?
Please check your wiring, make sure sensors are connected to the same port with your program in the WeeeCode software.
