Hello sir, I need your help. I have to make an app for my Control systems project in which I will control a solenoid door lock with the app. But the instructor has set some regulations that the lock should open when user enters correct pattern/password. In case of wrong password, the lock should be suspended for two mins. secondly it should send notification to another phone or in worst case on the same phone a notification should be displayed.

[@appinventor2tutorial]

In short - you can first check whether the password is entered in the [PasswordTextBox] (say after the Enter Password button is pressed). After that you need to check whether the entered password is correct (say by using the control [if] and comparing the strings [PasswordTextBox.Text] and [correctpassword]). Then you either open the lock or send a message, depending whether your comparison is true or false. Hope this is helpful - good luck.

Can you make it move by itself and bounce randomly

[@appinventor2tutorial]

Yes, off course. You can, say, set the initial [heading] to a random direction, as well as the random [speed]. The only catch is that you still need an event handler to initialize this motion, or you can set it in motion as soon as the app is initialized.
