Can NXT sensors be used with ev3?

6 min read

Asked by: Monique Nelson

Yes. LEGO® MINDSTORMS® EV3 uses the same LEGO TECHNIC elements and RJ12 connector cables as the MINDSTORMS NXT, so all your existing sensors, motors and building elements will work with the new platform, and the software will recognize them as NXT sensors/motors when they are plugged in.

Does NXT work with EV3?

LEGO® MINDSTORMS® Education EV3 NXT Compatibility

Some of the main features: EV3 uses the same RJ12 connector cables as the NXT, so all NXT sensors and motors will work with the new EV3 platform. EV3 uses the same LEGO Technic building system as NXT so you can reuse all of your bricks and other elements.

How can we use NXT sensors with EV3 brick?

For the EV3 brick, you can do it by using the Color sensor block and when using the NXT brick you can use the Light sensor with the Sound sensor block! You can even select between reflect and ambient light modes! Select dB for reflected light (LED on) and dBa for ambient light (LED off).

What sensors can the EV3 use?

The LEGO MINDSTORMS EV3 set includes three types of sen- sors: Touch, Color, and Infrared. You can use these sensors to make your robot respond to its environment. For example, you can program your robot to make a sound when it sees you, avoid obstacles while driving, or follow colored lines.

How do you use the NXT light sensor on an EV3?

If you want to use the NXT light sensor with the EV3 brick, you should use the color sensor block. If you put the color sensor block, set it to reflected light, set it to Port 1, delete the raw sensor value block and connect the two blocks, you will have a working program.

What does NXT stand for Lego?

The next technology – now

The next technology – now. LEGO MINDSTORMS Education features an advanced 32-bit computer- controlled NXT brick, Interactive Servo Motors, Sound, Ultrasonic and other sensors, Bluetooth communication and multiple downloading capabilities.

How does NXT touch sensor work?

The NXT Touch Sensor Multiplexer allows up to 4 touch sensors to be connected to a single NXT sensor port. An NXT program can read the state of each touch sensor or the state of all 4 touch sensors with a single read command.

How do you use a NXT light sensor?

The port tells the program what port the light sensor is connected to and where to look for the light value until basically allows you to set a value for the light sensor that it's measuring.

How does Lego gyro sensor work?

The digital EV3 Gyro Sensor measures the robot’s rotational motion and changes in its orientation. Students can measure angles, create balancing robots, and explore the technology that powers a variety of real-world tools such as Segway®, navigation systems, and game controllers.

What motors are used for the EV3 robot?

The EV3 Large Servo Motor is a powerful motor that uses tacho feedback for precise control to within one degree of accuracy. By using the built-in rotation sensor, the intelligent motor can be made to align with other motors on the robot so that it can drive in a straight line at the same speed.

Which is better NXT or EV3?

In general, LEGO MINDSTORMS EV3 is more powerful than LEGO MINDSTORMS NXT. If you do not have any LEGO MINDSTORMS sets yet, I recommend to go for EV3, so you’ll have the latest, most powerful LEGO robotics system to date.

What does EV3 stand for?


Acronym Definition
EV3 Evolution 3 (Lego)

What does the touch sensor do EV3?

The analog EV3 Touch Sensor is a simple but exceptionally precise tool that detects when its front button is pressed or released and is able to count single and multiple presses.

How do I connect my touch sensor to my EV3?

So here we have out the programming block for the ev3 touch sensor. And this is in my opinion the easiest sensor to use because it only ever outputs a value of 1 or 0.

How many sensors are there in EV3?

The EV3 Home (31313) set consists of: 1 EV3 programmable brick, 2 Large Motors, 1 Medium Motor, 1 Touch Sensor, 1 Color Sensor, 1 Infrared Sensor, 1 Remote Control, cables, USB cable, and 585 TECHNIC elements.

What are the 3 state of touch sensor?

In the Compare – State mode, you can choose which state of the Touch Sensor to test (Released, Pressed, or Bumped) in the State input. The True/False value of the selected state is output in the Compare Result.

How do you turn EV3 into 90 degrees?

And then we're going to set the exit case to the gyro sensor angle. And then choose greater than or equal to 90 degrees and then at the end we'll put a little stop.

How do you use Lego Mindstorm color sensor?


  1. Start the program.
  2. Start motors B and C (drive forward).
  3. Wait for the Color Sensor to detect the color red.
  4. Stop the motors.
  5. Wait for the Color Sensor to detect the color green.
  6. Repeat steps 2 to 5 forever.

What is move tank in EV3?

The Move Tank block can make a robot drive forward, backward, turn, or stop. Use the Move Tank block for robot vehicles that have two Large Motors, with one motor driving the left side of the vehicle and the other the right side.

What block is used for your robot movement?

The Move Steering block is used make your robot drive forward, backward, turn, or stop, it also adjusts the steering to make your robot go straight, drive in arcs, make tight turns or spins.

What is a steering block?

Steering Block attaches the Steering Shaft to the Upper Steering Support. The Steering Locks are placed on each side of the Steering Block, which are sold separately.

What is the LEGO EV3 medium motor used for?

The EV3 Medium Servo Motor is great for lower-load, higher speed applications and when faster response times and a smaller profile are needed in the robot’s design. The motor uses tacho feedback for precise control within one degree of accuracy and has a built-in rotation sensor.

How many rpm does medium motor give?

Medium-speed (200–1000 rpm) engines may operate on both cycles.

How do you use the infrared sensor in Lego Mindstorm?

Just like with the color sensor what it does is it gives us a data wire. Where this value is the output and it tells you the proximity of whatever the sensor is looking at in percentage.
