I am a teacher and I have just bought a Starter Kit Makeblock Robot.
I tried to write a simple program to avoid obstacles, but it seems that the ultrasonic sensor is not recognized. When I display ultrasonic sensor distance, it always is 400, no matter of the location of the obstacle.
I have read this comment below and I noticed that on the mainboard there is only red light ( Bluetooth version).
Can anybody help me with this problem?
By default, the lights on the mBot’s mainboard are green when in obstacle avoidance mode. If not, you are not in the correct mode. You can switch mode by pressing the black button on the mainboard or by using the IR remote controller.
