Connecting to a bluetooth speaker through mblock program

[vidb]

Hello,

We would like to play recorded sounds by connecting a small bluetooth speaker to the mbot and controlling it through the program. If anyone knows how we could do that, please let us know.

Thank you,
Vidhya

Quick search for previous discussions found these:

Speaker

The best way to accomplish this currently is to attach a small portable Bluetooth speaker to your robot. Then you can trigger the sounds in mBlock and play them through the computer, outputting the sound. to the Bluetooth speaker. You could also include a board like the Sparkfun MP3 trigger - This would allow you to eliminate the tethered computer. You would still need to add a small battery powered speaker to amplify the sound. –andrew

Play sound() on mbot

You’d pair the Bluetooth speaker to the computer you’re using, not to the robot. (mBot? Ranger?) I’m not sure if “tethered” is official makeblock terminology, but it’s what we use with students to describe programs written in mBlock running from a “When Green Flag clicked” block. These use an active serial connection (over Bluetooth, 2.4g Wireless Adapter or USB cable) to send commands to the robot and get data back. In tethered mode, you can use sensors on the bot to trigger actions in mBlock.…

The ME Audio player might solve your problem without using Bluetooth.

Thank you for the links! I found these useful but couldn’t find a way to communicate from the Scratch program to the bluetooth device (for eg., commands to operate the speaker). We actually tried with Alexa first before attempting to purchase a speaker.

Perhaps it requires additional software or some sort of a driver?

That looks like a good solution! Thank you for bringing it to my notice. I didn’t know such a thing was available. But now, where do I purchase it in the U.S.? I searched online and could find other accessories in Digikey, Robotshop,etc. but not this one.

Thanks,
Vidhya

No clue, ME Audio was hard to find in Germany as well. Maybe send a mail to Makeblock and ask them for a distributor.

I searched Amazon but looks like I didn’t observe carefully! Thank you for sending me the link!
