Turning a LED on and off with an Arduino, a HC-06 and Android | Martyn Currey. Although I use a HC-06 in the below examples the HC-05 in slave mode can also be used. Using MITs app inventor it is fairly easy to create an app that can turn a LED on and off from an Android device. This is a fairly simply example of sending commands to the Arduino to turn a LED either on or off. The Android app sends ascii codes to the Arduino via the HC-06 BT module; “ON” for on and “OF” for off. Load the app, connect to the HC-06 and then use the LED button to turn the LED on and off. You can also open the serial monitor to see the commands as they are received The steps involved are: 1. create a circuit that includes a Bluetooth module and a LED 2. create an Arduino sketch that can receive commands from the HC-06 and turn a LED on and off 3. create an Android app that sends commands over Bluetooth The circuit The circuit is the same as the one used in Arduino and HC-06 (ZS-040) except the addition of a LED + resistor connected to pin D12.
Arduino Sketch The full sketch: Android App Block 1. Android MIT App Inventor – Auto Connect To Bluetooth | Martyn Currey. In a previous post I showed how to connect an app inventor Android app to a Bluetooth module connected to an Arduino to control an LED. See Turning a LED on and off with an Arduino, a HC-06 and Android A few people have asked how to make it so that the app auto-connect to the Arduino on start up and I thought I would offer my solution. This example adds to the previous guide. The easiest way to add an auto connect would be to use a fixed address and put the connection function call in the Screen1.Initialize block. Since the Screen1.Initialize block runs automatically when the app is started, the app would try to make the connection every time it started. This is quick and easy but it means the mac address for the BT module is hard coded in to the app and to change the address you would need to change the app and recompile.
A better way is to allow the user to connect to any BT module and then save the address for next time. The App App Designer Screen The Blocks The Main Details Download.

App Inventor Designer App Inventor Blocks Edition. LEGO® MINDSTORMS® These components provide control of LEGO® MINDSTORMS® NXT robots using Bluetooth. LEGO and MINDSTORMS are registered trademarks of the LEGO Group. IMPORTANT: All of these components have a BluetoothClient property that must be set in the App Inventor designer (in the browser). The property cannot be set in the blocks editor. The property tells which BluetoothClient component to use for communication with the robot. You will need to explicitly add a BluetoothClient component to your project. If you have one robot, you should have one BluetoothClient component. Here's a list of the initial steps you'll need to perform to use one or more of the NXT components: Table of Contents NxtDirectCommands A component that provides a low-level interface to a LEGO MINDSTORMS NXT robot, with functions to send NXT Direct Commands Properties BluetoothClient The BluetoothClient component that should be used for communication.

MIT App Inventor is a web-based tool for creating apps for Android phones. The apps you create are stored on a server and can be downloaded to your phone or computer as well.
In this tutorial, we will teach you how to create an app for your robot. You could, for example, create a simple remote control that uses your phone’s tilt sensors to drive the robot. Note: Although this tutorial is based around using the NXT brick, the MIT App Inventor also supports the EV3 brick as well. Get started To start App Inventor, go to the site and log in using a Google account. Once logged in, you will have access to a range of tutorials includes one for creating an app to control a MINDSTORMS robot, but we have created a NXT-based project template for you where you can start programming an NXT robot at once. In App Inventor, press the More actions button and select upload source: Browse to where the NXT_Template.aia is located, select the file and press OK. The designer screen. 6858 191 p16.
