![]() ![]() ![]() Use the sensor value block in the Sensing category, selecting tilt from the pull-down menu. Tilt Sensor: The tilt sensor can be used to determine orientation, where 0 is flat, 1 is down, 2 is right, 3 is up, and 4 is left. ![]() Use the sensor value block in the Sensing category, selecting distance from the pull-down menu. Below are some videos to get you started Getting Started with Scratch 3.0 Programming a WeDo 2.0 Medium Motor with Scratch 3. Distance Sensor: The distance sensor can be used to determine proximity, where 0 is close and 100 is far. Troubleshooting WeDo 2.0 and Scratch 3.0 Combining playful hands-on experiences with creative coding exploration, you and your students can easily connect WeDo2.0 with the Scratch 3.0 release from MIT.You can use the blocks to turn the motor on and off, set the motor power, and set the motor direction. If not, select Show Motor Blocks from the Edit menu. Motor: The WeDo motor blocks should be visible in the Motion category.Controller: Connect the WeDo controller to your computer via USB.This guide is intended to be a quick overview of the WeDo components (controller, motor, distance and tilt sensors) and how to control them via Scratch. Scratch version 1.4 has special programming blocks to interact with motors and sensors in your LEGO WeDo robotic creations. Curricular Areas: Computer Science, Engineering, Language Arts, Mathematics, Music, Science, Social Studies, Teacher Education, Technology, Visual Arts, Other.Content Types: Handout, Reference Guide, Tool, Website.Education Level: Preschool and Kindergarten, Elementary School, Middle School, High School, College and University, Professional Development, Other.This block reports the angle at which the WeDo has been tilted in the specified direction (unlike other tilt blocks, "any" cannot be selected here) This block reports whether or not the WeDo is tilted in the specified direction. "everything" controls all connected motors and lights. "light" controls the lights regardless of where they are connected on the WeDo hub. If two motors are available but need to be controlled separately, "motor A" can be used with one and "motor B" with the other. If only one motor is available, use the "motor" option, which will control the motor regardless of where it is connected on the WeDo hub. Reverse switches the direction.Īll motor blocks have a menu that allows control over two WeDo motors and lights separately. The first two are equivalent to clockwise and counter-clockwise. There are three options for the direction, listed as "this way", "that way", and "reverse". This block sets the direction that a specific motor should turn with. This block sets the power of a specific motor or the lights, controlling the speed at which the motor is spinning or the brightness of the lights. Turn a specific motor or the lights on indefinitely. There are five options for the block, listed as "motor", "motor A", "motor B", "light" and "everything". Turns a specific motor or the lights on for a certain amount of time. Note: Scratch 2 offline editor now supports LEGO WeDo. There is more information about the LEGO WeDo, including sample projects and more detailed instructions on setup, on Scratch here. Once the LEGO WeDo extension has been added, the Tips window will open and give the link to the Extensions installation instructions. Click "Add an Extension" and choose "LEGO WeDo."Ī plugin is needed to use any hardware extension. The LEGO WeDo extension can be added within the "More Blocks" category. The LEGO WeDo Construction Kit can be used with the online editor of Scratch 2.0 by adding an extension. It is only useful from a historical perspective. This article or section documents something not included in the current version of Scratch ( 3.0). Used to connect the WeDo parts to a computer. Interact by moving closer and further from this sensor. These are LEGO Power Function lights that are not included in the WeDo kit, but can still be connected to the WeDo hub and controlled using Scratch. ![]()
