7.4 problems


My seven year old has hit a wall on 7.4, and we cannot progress past this. No idea of what’s wrong.

It’s mBot starter.




Hi Riny4,
Please make sure the line follower sensor is connected to port 2, and two lights on when mBot is placed on a white paper. Once you pick it up, lights will be off. If still have issue, you may try to reset default program in PC software,
