First time user ...not going so well

Holy Sh*t I even changed a stock program for the ultrasonic car to make it drive slower but turn quicker.

I have a 2 cell lipo running it rather than the alkaline cells.

This is getting exciting!

Hooray - Good times! Now that you have the ‘hard way’ (Arduino) mastered, you will find mBlock an easy way to build your programs.

Set up mBlock for the Makeblock Orion if you haven’t already, and start on sensors and lights!

Cool Cool Cool

See, I told you it is fun to actually “make” something, rather than using what others made.

Now you should also find a “firmware” sketch somewhere in your libraries. Try to upload this one (it will not damage anything), plug in the BT cable on the bot and try to control the bot from your IPad or Android device with the app. I can not be sure it will work but it’s worth the gamble in order to motivate your son. If the firmware doesn’t work, just upload one of the other sketches (or an own one) again and keep having fun.

I am rather into the hard way of programming (Arduino IDE) than into the mBlock or Scratch way of doing things. But as you are a beginner and your son just 10 this will indeed be the very best tool to create sketches for the bot together with him.

Have fun!

I would like to thank everyone that contributed to this thread. I had nearly exactly the same problems, but with your guidance it all worked out!

Thanks

Well we have 2 days history mBot and my sons and me!
After assembling the set it was working fine with the Android Mobile App. using BT connection. 
All the functions worked well (Line follower and the Ultrasonic sensor base part also).  

Than we connect the mBot to mBlock 3.2.2. with USB and upload the firmware. We did some programing (giving command to M1 and M2 motors) everything was OK.

After we disconnected the USB the Mobile App based “Unmaned and Track” functions did not work. The manual control was okay but it looks there are some issues connected to the Ultrasonic sensor and the Line follower occur.

I have done the “Reset Firmware” many times but no progress.
I have tested the Ultrasonic sensor itself (red LED is lights on the sensor) and it shows the distance on the screen as well.

One more thing: I was not able to switch on the LEDs on the board… it looks I have an issue here as well.

What shall I do now?

For my mbot, after I “Upload the Firmware” so I can use Makeblock (the picture-puzzle blocks for programming over bluetooth or wireless), then the little IR remote no longer works. But I could make it work again by going back to using serial communication from the computer to the mbot over USB and then “Reset Default Program” in the Connect menu. My understanding is that this loads a program into the arduino that responds to the IR signals from the remote. But doing that replaces the “Firmware Update” program that allows Makeblock programming. So you have to choose one or the other (but of course you can switch back and forth by connecting with USB serial communication and uploading the appropriate program to the arduino). Hope this works for you.
