Exploring Lego Wedo: A Creative Guide For Beginners

LEGO WeDo is a robotics kit designed for elementary students aged 7 and above. It is a wireless solution that utilizes low-energy Bluetooth technology to communicate with tablets, laptops, or desktops. The kit includes a SmartHub, a medium motor, and motion and tilt sensors. Using the LEGO WeDo software, children can create programs by dragging and dropping colourful code blocks, which represent different actions, conditions, and events. This hands-on approach helps children understand the relationship between code and action, introducing them to key programming concepts such as loops, conditional statements, and variables. While the kit is designed for children, it can also be used by adults for innovative STEM education projects.

LEGO WeDo is designed for elementary students ages 7+

LEGO WeDo 2.0 is a hands-on science solution for elementary students ages 7+ that combines the LEGO brick with classroom-friendly software and curriculum-relevant science projects. The kit includes 280 LEGO system building elements, a low-energy Bluetooth Smarthub, a medium motor, and motion and tilt sensors. The Smarthub can communicate with the WeDo 2.0 software through low-energy Bluetooth technology, allowing students to build, program, and modify projects wirelessly.

The WeDo 2.0 kit is designed to enhance students' practices within Science, Technology, Engineering, and Math (STEM) by encouraging problem-solving through investigation, modelling, designing, and computational thinking. Students can explore, create, and share their scientific discoveries, building confidence to ask questions, define problems, and design their own solutions.

The WeDo 2.0 app and software, available on the Google Play or Apple App Store, provide curriculum material for computational thinking. Teachers are also supported through training, curriculum, and built-in assessment.

To use the WeDo sets, students will need access to a tablet or laptop. The kit is a wireless solution, allowing students to connect up to three Smarthubs to one device simultaneously. With one brick set, students can connect one motor and one sensor or two sensors.

The WeDo 2.0 Core set comes with 280 LEGO elements, a Smarthub, a medium motor, and sensors

The WeDo 2.0 Core set is designed for elementary students aged 7 and above. The set comes with 280 LEGO elements, a Smarthub, a medium motor, and two sensors: a motion sensor and a tilt sensor. The Smarthub utilises low-energy Bluetooth technology to communicate wirelessly with the connected tablet, laptop, or desktop. The tilt sensor has six different positions and a new shake mode, while the motion sensor can detect objects moving closer or further away.

The medium motor can be programmed to turn both clockwise and counter-clockwise and to move at different power levels. LEGO bricks and other elements can be attached to the motor. The motor can be connected to the Smarthub, along with one sensor or two sensors. It is recommended that only one motor is connected to a hub to limit power consumption.

The set comes with a sorting tray and labels, and the accompanying software provides an easy-to-use programming environment. The software includes a Get Started Project, which helps users become familiar with the hardware, software, and documentation tool. The WeDo 2.0 Curriculum Pack covers life, physical, earth, and space sciences, as well as engineering.

The Smarthub uses low-energy Bluetooth to communicate with tablets, laptops, and desktops

LEGO WeDo 2.0 is a wireless solution designed for elementary students ages 7 and above. The Smarthub, a key component of the WeDo 2.0 set, utilizes low-energy Bluetooth technology to communicate with tablets, laptops, or desktops. This Bluetooth functionality allows the Smarthub to connect seamlessly with the WeDo 2.0 software, enabling users to control their creations wirelessly.

The Smarthub's low-energy Bluetooth capability offers several advantages. Firstly, it ensures a stable and efficient connection with the device being used, whether it is a tablet, laptop, or desktop. This compatibility provides users with flexibility and the ability to choose their preferred platform for interacting with their WeDo 2.0 models.

Additionally, the low-energy aspect of the Bluetooth technology optimizes power consumption. This feature is particularly important considering that the WeDo 2.0 models are designed for young learners. By conserving energy, the low-energy Bluetooth technology prolongs the battery life of the Smarthub, enhancing the overall user experience.

The Smarthub's ability to communicate via Bluetooth also facilitates the integration of various sensors and motors. While using the WeDo 2.0 set, users can connect one motor and one sensor or opt for a combination of two sensors with a single brick set. This flexibility in sensor and motor connections empowers users to create more complex and interactive models.

Furthermore, the Bluetooth functionality of the Smarthub enables simultaneous connections with multiple devices. Up to three Smarthubs can be connected to a single tablet, laptop, or desktop, allowing for collaborative work and the ability to control multiple WeDo 2.0 models from a central device. This feature encourages teamwork and enhances the educational potential of the WeDo 2.0 set.

The WeDo app lets kids control their creations using the Tynker programming language

LEGO WeDo 2.0 is a wireless solution that allows users to control their creations using the Tynker programming language. The WeDo Smarthub utilises low-energy Bluetooth technology to communicate with connected tablets, laptops, or desktops.

To get started, you will need a LEGO WeDo 2.0 Core Set, which comes with 280 LEGO system building elements, a Smarthub, a medium motor, a motion sensor, and a tilt sensor. You will also need a tablet or iPad that supports Bluetooth 4.0.

Once you have your hardware, you can download the Tynker app from the App Store. Make sure to download the most recent version, as older versions do not support WeDo 2.0.

Open the Tynker app and select the "Workshop" section to start a new blank project. Add an Actor to represent the WeDo by selecting the "+" sign, choosing the "Connect Device" category, and selecting the WeDo as the Actor. You can now click on the "Code" button and see that it comes with some initial code.

Turn on your WeDo by clicking its on/off button, and it should automatically pair with your iPad via Bluetooth. Once paired, you will see a green indicator on the WeDo Actor in your Tynker project, and the light indicator on your WeDo will be on but not blinking.

Place the WeDo on a flat surface with enough space in front of it to move. Click the orange "Play" button on your Tynker project to run the default program, which will show an image of the WeDo brick. Touch the image of the brick to make the physical WeDo move. You can now create your own programs by combining different blocks of code.

You can also use Arduino or Raspberry Pi to control your WeDo 2.0 creations

LEGO WeDo 2.0 is a wireless solution designed for elementary students ages 7+. The Smarthub utilises low-energy Bluetooth technology to communicate with the connected tablet, laptop, or desktop.

While LEGO WeDo 2.0 is typically controlled via an app, it is possible to use Arduino or Raspberry Pi to control your WeDo 2.0 creations. All of the Powered Up elements communicate via a Bluetooth protocol that TLG provides documentation for.

If you have an Arduino, you can try the Legoino project, which is capable of interacting with both Powered Up remotes and Powered Up hubs. This allows you to program the Arduino to interface between the two and provide remote control.

For those with a Raspberry Pi or a spare computer, node-poweredup or pylgbst may be worth exploring. Additionally, when using Python with the WeDo 2.0, a BLE library is required. While BLE support in Python is still quite immature, there are libraries like gattlib that work in ev3dev.

It's important to note that Bluetooth Low Energy (BLE) support is not available in Linux virtual machines on VMware Workstation. However, you can use command-line tools like hcitool and gatttool to scan for Bluetooth devices and test connections.
