This tutorial lets you make an app that drives around an EV3 LEGO robot by tilting a phone or tablet. Tilting forward makes the bot go forward, back --> back, right --> right, left -->left. A steeper pitch will make the robot drive faster… etc.
In this 3-minute video, App Inventor Developer José Dominguez shows you how to use the File Sharing component in App Inventor 2 to share text and/or files from your App Inventor app to any messaging-capable service on your device (e.g. Gmail, Twitter, G+, WhatsApp, Messaging, etc.).
QuizMe is a trivia game about baseball, but you can use it as a template to build quizzes on any topic. This tutorial is especially useful for learning about working with information in Lists. Lists are useful data structures for keeping track of many items of the same type, especially when you want to cycle through those items.
The location sensor object is used to communicate with the global positioning satellite receiver (GPS) in your phone/tablet. When the LocationSensor communicates with the built-in GPS receiver, the GPS can determine the location of your device. The sensor can also work with network/wifi location services. Finding a location using the network uses very different techniques to determine a location. Location means, the device's present latitude and longitude or it can mean your street address.
This tutorial shows how you can develop an app that allows you to record list of addresses and view the address on the Google Maps. It will also show you how view your current location on the Google Map.
You parked somewhere near the stadium, but when the concert ends you don't have a clue where the car is. Fortunately you haven't lost your Android phone that never forgets anything, and you remember you have the hot new app, Android, Where's My Car?. With this app, you click a button when you park your car, and the Android uses its location sensor to record the car's GPS coordinates and address. Later, when you reopen the app, it shows you a map from where you are to the remembered location-- problem solved! With this tutorial you'll be able to download a created app and then study the annotated blocks below to better understand the app and App Inventor programming in general. This app covers: GPS, TinyDB, and using Activity Starter to open a map.
This tutorial will demonstrate App Inventor's Near Field Communication (NFC) capabilities. You'll build an application that will simulate the shell game by writing messages to NFC tags in setup mode and reading them in play mode. In order to get the full experience from this application, you will need to purchase readable, writable, NFC tags.
