My son and I were working on getting the mbot setup and trying to learn some of the basics but are a bit confused.
We were able to get the usb cable connection made to the robot and get the firmware upgraded. in addition, i was able to upload a small program to the unit and have its wheels turn.
We then proceeded to try and get the wireless 2.4g module working. Disconnected usb wire, plugged in the white usb device and on the mbot the blue led on the wireless module went solid blue. seemed to have a connection. We were watching this video: https://www.youtube.com/watch?v=kiO8VYpIGsw (video seems to be using perhaps a previous version as ours does not look the same. ) but we do not have a light intensity option so in its place were trying the ultra sonic sensor in its place. We would set the program up, click the green flag and the bear would show a zero, move our hands in front of the ultra sonic sensor (eyes of the unit right?) but it would not change.
What are we doing wrong and is this wireless 2.4G truly connected and functioning? Is this what the intent of the 2.4G unit is to program the mbot without being connected with a wire?
Also, when we first tried the unit we were able to use the remote to move the unit, do the wall avoidance, etc. Did upgrading the firmware delete these as the remote functionality does not work at all even when the a, b, c buttons are selected.
Do we simply need a 6V power supply withe right end to use an external power supply as we may have one laying around? I have a 5v plug that would fit it seems. Would this work sufficiently?
Thanks and hopefully we can get around some of these simply things that he can start programming and using the unit again.
