Arduino With L298N Based Dual Motor Controller The ControllerA motor controller is a device that serves to govern in some predetermined manner the performance of an electric motor. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, regulating the speed and torque, and protecting against overloads and faults. This Dual Motor Controller is easy to use, thank's to the L298N motor driver chip. This chip allows for direct drive of two bi-directional DC motors, and incorporates high-speed short diodes for protection. Drive current up to 2A per motor output. The driver uses a broad-brush design to reduce wire resistance.Below, an illustration of the DRI0002, an inexpensive board avalaible by DFRobot. Click the image to enlarge Each motor is controlled by two pins on the motor controller: A pin M, (zoom the above picture, look at the motor logic) that affects the polarity on the output terminal of the corresponding motor.

Arduino Shield List NetIO Controller Here are some examples of hardware which has been used with this app. If you want to test your hardware and write a small tutorial about it, please ask for a promotion code to get the app for free. Also, many users have submitted their projects including instructions and configurations. Server / PC This tutorial sets up a simple Java socket server and connects the NetIO App to this server. 1. Make sure you have the latest Java JDK installed on your and download the VerySimpleServer.java 2. Go to the folder you saved the file and run javac VerySimpleServer.java in your terminal. 3. Type "java VerySimpleServer 54321" into your terminal. 4. Open the helloworld.json in the UI-Designer and edit the host name (ip address) in the connection. The host attribute should be the name or the ip of your computer you started the server. 5. Start the app and hit the "Hello World"-Button. Arduino I found a nice project on (german) which uses the NetIO app with an arduino board.

NetIO UI-Designer The designer is a tool to create configurations for the NetIO applications. It helps adding and layouting items, as well as adding functionality to these items. The overall process of creating a new configuration can be seen in the video tutorial. Once you created a new configuration you can click the button to add the configuration to your user profile.Important: Changes made in the designer are not automatically saved. On the app side, enter your UI-Designer credentials and hit the 'sync' button to download all your user configurations. The designer can be used with or without being logged in to a user account. The button opens a pop-up menu which shows all available configuration presets and if logged in, all user configurations. Help to specific attributes can be retrieved through clicking the sign in the according form. The buttons can be used to upload existing configuration files (JSON) or download the edited configuration back to your computer.

NetIO Controller This section describes the JSON structure used to store configurations. In most cases, using the UI Designer should do anything you want. In the UI-Designer, there is also a small help icon ( ) beside every attribute showing a small explanation on mouse-over. Don't wanna read? Check out the short introduction on youtube! Short API-like auto-generated docs See the auto-generated docs for getting a quick overview over available attributes. General Remarks The App is called NetIO, but the name displayed on your device is just 'Controller'. Handling multiple configuration files and sync with online UI Designer When seeing the first page, a swipe to the right opens the configuration menu on the left. Testing If you want to test the iPhone/iPad/Android application, simply start a socket server on your computer like descriped in the Tutorial section. How does the app work? The app renderes different items on the screen. Configuration This is the overall JSON structure. Connections Items Buttons Icons ...
