The EV3 has four input ports for connecting sensors and other devices (like sensor multiplexers or motor controllers). If you are trying to use something that plugs into one of those ports, you are in the right place. When dealing with sensors in ev3dev, it is useful to know how it communicates with the EV3 brick. There are four basic kinds of communication that the input ports can use to get information from the sensor: analog, NXT Color Sensor, I2C These are the simplest type of sensor. The measured value is converted to a voltage (0-5VDC) that is read by the EV3. There are actually two types ofWe call the first EV3/Analog. These are sensors that were designed specifically for the EV3 and will not work on the NXT because theThey contain an ID resistor so that the EV3 can tell different types of sensors apart. The second type is NXT/Analog. sensors are designed for the NXT, but also work on the EV3. differentiate between most of these sensors though, so you have to tell it
which one your have or just use the generic driver. WeDo sensors, referred to as WeDo/Analog, are also analog sensors. actually electrically similar to EV3/Analog sensors (require 5V power and haveCurrently, we only support WeDo sensors attached to a WeDo hub, but if someone would like to design a cable and modify the wedo-sensor and lego-ports drivers, we could easily make them work with the input ports on RCX sensors also fall into this category, but do not work with the EV3 - at least not with the converter cable described in the NXT Hardware DevelopersThis is due to a difference in the input port pins between the EV3 andIf someone wants design a new converter cable, we could make them work. The LEGO NXT Color Sensor is in a class of its own. It uses a hybrid of analog and (non-standard) digital communications. The NXT Color Sensor is not usable at this point in time. We can detect it with the auto-detect, but we don’t have a driver for it yet.
I2C sensors are sensors that communicate with the intelligent brick via theIn the NXT documentation, they are referred to a “digital”These sensors can be sorted into two categories as well: those that were designed using LEGO’s guidelines and those that use an off the shelf I2Cev3dev supports both kind of sensors, but only the first type isWe will refer to the former as NXT/I2C and the latter as These is a new type of sensor that is designed specifically for the EV3 (they don’t work with the NXT). They use an UART to send data to the brick. sensors are a bit “smarter” in that in addition to sending the data of what they measure, they also send information about their capabilities. that any new EV3/UART sensors should “just work” without us having to writeSince the ‘U’ in UART means universal, this also means that EV3/UART sensors can connect to any UART device, not just the input ports. The EV3 has “smart” sensor ports that can identify most sensors.
Full automatic detection works on EV3 only. And even on EV3, some sensors cannotSee notes below in the table of supported sensors. For sensors that cannot be automatically detected, you can manually control the input port mode. Read more about it on [the lego-port class page][lego-port-class]. On FatcatLab’s EVB, only EV3 sensors can be automatically detected. sensors, you must manually set the mode. (I2C sensors currently do not work on On BrickPi, sensors cannot be automatically detected at all. configure the input ports for all sensors. On PiStorms, detection of EV3/UART, EV3/Analog and NXT/I2C sensors is semi-automatic. put the input port into ev3-uart, ev3-analog, or i2c-thru mode, the specific type of sensor will be automatically detected (assuming it is a LEGO compatibleSo you don’t have to write to the set_mode attribute of the port for One of the goals of ev3dev is to support as many sensors as possible. even if a manufacturer’s documentation says that a device does not work with
the EV3, chances are it will work with ev3dev. If you have a sensor that is not supported yet, let us know about it by opening an issue on GitHub. For many sensors adding a driver is trivial - even if you are not a “kernel hacker” or a “c programmer”. sensors, see the contributing page for information on how to write a driver or how to donate hardware to someone who will.

an overview of the programming environment, then explores the usage of motors andWhile the course videos use the new LEGO EV3 kits, all challenges can also be accomplished with the older LEGO NXT kits.

Please send feedback, suggestions, improvements, and adaptations to Dr. Tanja Karp This course was developed during the summer and fall of 2014 through funds provided by the Halliburton Education Foundation. It was offered during Fall 2014 as an online course for coaches participating in the Texas Tech Get Excited About Robotics (GEAR) competition or the Texas Computer Educator Association (TCEA) robotics competition in Lubbock. Videos and challenges for this course were developed in collaboration with Guthrie Virtual School. Special thanks goes to Darren Wilson and his daughter, Laura, for the creation ofThere are two ways to implement the WaterBotics project—a programming track and a non-programming track.
The programming track makes use of the MINDSTORMS® NXT module, sensors, and software, while the non-programming track relies instead on the Power Functions Infrared (IR) remote controllers. The choice of which track to take will have a significant impact on the equipment needed as well as the cost. The materials that are needed for both the programming and non-programming tracks are shown below. Each item is linked to a possible source to help you obtain individual parts. For your convenience, we have secured agreements with LEGO® Education and Pitsco Education to offer the LEGO® and other supporting materials as pre-packaged kits. At this time, the LEGO® kit only includes LEGO® components suitable for the non-programming track of WaterBotics. The Pitsco kit includes all of the non-LEGO equipment needed for WaterBotics. If you do not have any WaterBotics equipment, you will need to purchase both kits. Each kit provides enough materials to build 5 robots, which should work well for a class of 20 students, assuming 5 teams of 4 students each.
Important: As of January, 2016, LEGO® Education no longer sells the MINDSTORMS NXT component. NXT components may be available through other re-sellers such as on Amazon but purchase cannot be guaranteed. For those who already have NXT equipment, the additional equipment needed for WaterBotics is listed below. Note that the Non-programming Track of WaterBotics is not at all affected by the discontinuation of the NXT. For the other supporting materials, Pitsco offers two different pre-packaged kits that can be used for both the programming and non-programming tracks. The NXT has been replaced by LEGO's EV3 component. The EV3 version of the WaterBotics curriculum is anticipated to be released by Stevens in the Spring, 2017 and updated equipment lists will be available at that time. In addition to obtaining the necessary equipment, the WaterBotics curriculum must also be purchased. Please see Purchase a License for more information. Please contact us if you have any questions about these materials.
