Can you explain friction? Is it easier to pull something on a normal surface than on a slippery one?.To make it move, pull or push it, or, more generally, apply a force to it. What are some ways you can make an object move?.This is the part that says ‘wait until something comes close’. Click on the block to change the direction of the arrow, until the arrow points towards the sensor. Remove the blue number block from the bottom, and replace it with the small orange motion sensor block. This gives us a pretty good idea of how to structure the blocks. Keep moving forward until that something moves away again, then stop. Wait until something comes close, then move forward. The instructions for the reindeer go something like this: It really helps to think through the instructions like a sentence before you start. Now, let’s have a look at what we want the reindeer to do. There’s only the one line of code for this, so the arrow works perfectly. Let’s get started!Įssentially, this is a one-line code, which is awesome! It’s also detailed below, so keep reading if you would like to know a bit more about how it works. We walk you through the code step-by-step in the Lego WeDo app. If you want to follow along with video instructions, have a look at the second half of the video at the top of this post. The reindeer uses a very straightforward piece of code, so you can put it together very quickly. Importing the custom blocks for Lego WeDo lets you combine them with standard Scratch blocks to extend what you can do. Scratch is a block-based coding platform, which has the ability to integrate with a wide range of hardware options including Lego WeDo, Mindstorms and Boost, BBC microbit, and Makey Makey. If you want to start coding more complex actions, consider using Scratch instead. There is limited complexity that can be achieved within the WeDo app, as it’s designed for simple instructions and getting started. In terms of outputs, the motor can activate, a display can show on your devices screen, or the colour of the light on the smarthub can change. A range of inputs can be used, including from the tilt sensor, motion sensor, noise sensor (from your devices microphone), or from the ‘go’ button. The platform is very simple to use, with blocks aligned side-by-side in the sequence you want your project to execute the instructions. The Lego WeDo 2.0 kit comes with an app for pictorial coding, which lets you get your projects up and running quickly.

He uses the motor for his movement, with gears driving his front axle, and the Lego WeDo smarthub sits on his back. As long as you’ve got the kit, you’re ready to get started right now. The reindeer uses no Lego pieces other than what’s in the standard Lego WeDo 2.0 core kit. The app is a very big download, just under 500MB, but once you’ve got it installed, it’s very easy to set up and get started. For us, a big benefit of having the project instructions within the app is that they’re all in one place, and they can’t get lost or damaged. The app contains instructions for heaps of WeDo projects, and an image-based coding platform that communicates with the smarthub via bluetooth.

As you would expect, it’s compatible with all the standard Lego and Technic components.Īlongside the kit comes the Lego WeDo 2.0 app.

The core kit comes with a smarthub, motor, tilt sensor and motion sensor, plus a range of gears, wheels, axles and bricks to create a wide range of projects. Lego WeDo 2.0 is Lego’s entry-level robotics & coding kit, designed for the education space.
