Using android mobile to control arduino

I'll update it one day but my friend borrowed the bluetooth module for some experimenting so it might take a while.

You can still access the older version of app inventor here -> http://beta.appinventor.mit.edu/
And here are all of my projects -> Electronics - Google Drive

Just use the older version to see what blocks I used and what they do and rebuild it in the newest version. Or just use the old one
