EV3 Next Steps

The EV3 Software has two components: Programming and Data Logging (perform experiments).

Program a robot: Without a program, a robot is just a statue. It may be a cool statue, but it’s still a statue. When you program a robot you give it abilities— to move, to follow lines, to avoid objects, to make mathematical calculations, and much more. The EV3 Software has an intuitive, graphics-based, drag and drop format.

Data logging is the process of acquiring and recording data.To data log is to collect information for analysis. For example, a weatherperson might collect temperature readings throughout the day, and then analyze it for a report on the evening news. Or a zookeeper might collect data on where visitors are spending their time at the zoo. The EV3 Software cannot only record data, it can help you to organize and analyze it.

Get started with two experiments. 1 using the color sensor and 2. the ultrasonic sensor.

Data logging is the collection of data over a period of time, and is something often used in scientific experiments. Data logging systems typically monitor a process using sensors linked to a computer. Most data logging can be done automatically under computer control.

Oscilloscope Mode . . . From LME SOFTWARE

Oscilloscope Mode lets you see the sensor values for the sensors connected to the EV3 Brick in real time.

Start/Stop Oscilloscope Mode to turn it on and off.

When Oscilloscope Mode is enabled, the Graph Area will turn blue and any existing graphs will be faded into the background. Data plots will be shown as dotted lines and will update continuously. The following image shows data from two Motor Rotation sensors, for a robot being pushed forward.

A TIP: You can also use Oscilloscope Mode to see how the other sensors respond. For example, try moving the Color Sensor over a picture. You will see the readings in Oscilloscope Mode in real time.
