“One on the donkey the other pulling the donkey. “I can see two people on a donkey,” said Tommy. Suddenly they were falling out of the sky. “We need to get them going back to Bethlehem.” Then the room started to shake. “It says we have to save Christmas because Mary and Joseph are heading in the opposite direction of Bethlehem.” Tommy took a breath and carried on. ![]() ![]() There was a big machine with an old looking elf beside it. They snuck down to the basement and opened the door. “We’ll just see what the glow is ok,” said Tommy. “ I don’t know,” worried Lee, “My mammy told me not to go down there”. They saw a blue glow from the coming from the basement.” Let’s go,” said Tiernan. Lee was on so he chased him all through the house. Tommy, Macdara, Lee, Colm H and Tiernan were playing together at Lee’s house. Keep checking the motion sensor for changes, and change the speed as needed.It was Christmas Eve. When the green arrow is pressed, start the motor, and set it to whatever speed the motion sensor detects. Just like the reindeer, it helps to think of the code like a sentence. You only need one line of code, and a couple of blocks. It’s a very simple piece of code, and it took him no time at all. Coding the Sleighįor the sleigh, Liam used the Lego WeDo app. 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. Send me the FREE instructions!
