I have an App Inventor app running on my Nexus 5 and talking to an Arduino board via Bluetooth. I finally had a chance to work on this! UPDATE: Here is the link to the final code and tutorial information! What I have now is some experimental code not suitable for posting online. I will … Continue reading Coming soon: Bluetooth to connect Android App Inventor code to Arduino
Part 1 of this tutorial introduced Bluetooth communications and implemented a simple method of sending text data back and forth between two Android devices over the Bluetooth wireless link. If you are not familiar with using App Inventor’s Bluetooth component, start with Part 1. In Part 2, a data packet concept is introduced to guide … Continue reading Part 2: Sending numeric data using App Inventor Bluetooth communications
(Some very minor updates were made to this in November 2019). This tutorial covers basic App Inventor Bluetooth communications code. Subsequent tutorials will add additional features. To implement and test this sample code, you need access to two Android devices – one to act as a Bluetooth “server” and the other to act as … Continue reading Part 1: Basic Bluetooth communications using App Inventor
Android phones and tablets support Bluetooth communications (“BT”). BT is a very low power, very short range communication technology used for connecting earphone and headphone adapters, wireless microphones, and wireless keyboards and mice to computers and tablets. App Inventor supports BT links and can be used to transmit data back and forth between two Android … Continue reading App Inventor Bluetooth Communication tutorial coming soon
This web site – appinventor.pevest.com – is no longer the primary web site for our App Inventor tutorials. However, this web site will remain here indefinitely as many people link to it, including search engines and including my own e-books 🙂
Part 1 showed how to reference and store user interface components as a variable. That tutorial used this method to easily change the background colors of six buttons on screen. In Part 2, we use this technique to simplify a past tutorial about using a Bluetooth link between and Android device and two Arduino devices.
