EV3nts - EV3 Sensors (com.redroundrobot.ev3nts) on Google Play
It is a great and very affordable way to create cool science projects.A great substitute for all those expensive sensors! An all in one solution.After you establish the connection to the brick you can turn on your desired sensors on your device and the EV3 will receive the messages:- get the x,y and z values of the Accelerometer and Gravity- get the rotation angle along the x,y and z axes ( degrees ), also known as Euler angles- get the rotation speed along the x,y and z axes ( degrees per second )- use your device as a compass that will send you feedback of its position relative to the Magnetic North.You can use it with the official LEGO Mindstorms EV3 Software programming environment or with any other programming languages available: LeJOS, RobotC etc.Visit our page to see video demos and download the custom sensor blocks: http://redroundrobot.com/EV3nts.htmlNote: not all sensors are available on all devices. Make sure your device has the sensor you are interested in using. The app will work with the available sensors.
