Please note that when many users in a single location, like in a classroom, are downloading programs at the same time, you may experience slower internet speeds. You can learn more about the error messages in EdScratch in our tutorial videos and in the EdScratch warning messages guide.

If you have a red warning message in the ‘bug box’ at the bottom of the EdScratch app, you will not be able to download the program until this critical issue is resolved. Follow the step-by-step guide on setting up your device for EdScratch beginning on page 6 of the Getting started guide. Make sure your programming device is set up to work with EdScratch. Comments are designed to be used as useful ‘sticky-notes’ helping the programmer and others understand the program.ĭepending on the type of computing device you have, there are a few different things that can cause problems downloading programs with EdScratch. Comment blocks are ignored by the compiler and have no affect on the EdScratch program. The pink block in the Comment category allows you to add in text comments as notes in a program. The Operators category blocks include expressions and computation operators designed to be used with sensing and other data inside programs. The green blocks in the Operators category are all blocks that can be used as either value inputs (oval shaped blocks) or Boolean inputs (diamond-shaped blocks) inside blocks in an EdScratch program. These blocks allow you to turn different sensors on or off, clear stored sensing data and use sensing data as value inputs (oval shaped blocks) or Boolean inputs (diamond-shaped blocks) inside blocks in an EdScratch program. The light blue blocks in the Sensing category are all related to the Edison robot’s various sensors. Loops, waits and if-statement control blocks can all be found in the Control category. The light orange blocks in the Control category are all programming control structures which can be used to affect the flow of an EdScratch program. The yellow blocks in the Event category are all sensor-related event blocks that can be used as interrupts beginning subroutines in EdScratch programs. Once a variable has been created by using the ‘Make a variable’ button and giving the variable a name, the Data category is populated with dark orange blocks related to data manipulation using any created variables. Initially containing only two buttons, the Data category is how you make and manage variables in EdScratch. Single beeps, musical notes and blocks which control only music note blocks are all in this category. The light purple blocks in the Sound category are all related to the Edison robot’s audio outputs. Both the visible light (red LEDs) and infrared LEDs outputs (for IR messaging) can be controlled using blocks in this category. The dark purple blocks in the LEDs category are all related to the Edison robot’s LED outputs. The dark blue blocks in the Drive category are all related to the Edison robot’s motor outputs. The following vocabulary definitions are from the Scratch Wiki.All of the blocks in EdScratch are arranged into one of the nine different block categories in the block pallet. Moving their sprite up and down using the arrow keys.Every Scratch project whether it be a game, story or animation will always have the x,y grid behind the stage to determine where sprites are located. The “X coordinate” value determines the horizontal location of the sprite and the “Y coordinate” value determines the vertical location or height.

Both the Code Area and the Stage are visible at the same time which allows learners to run code, test, debug and view their creations.Īccording to the Scratch Wiki, Scratch’s coordinate system uses 2 coordinates, “X coordinate” and “Y coordinate”, to determine the location of a sprite on the stage. These code blocks can be pieced together in the Code Area like placing jigsaw puzzle pieces together. The code blocks are grouped by the following categories: Motion, Looks, Sound, Events, Controls, Sensing, Operators, Variables and My Blocks. Scratch makes it easy for learners who are just starting out by organizing the types of code you can use into categories. In this series, the basics of Scratch will be introduced to provide learners with the foundational skills required to begin creating in Scratch. In using Scratch, learners will be introduced to basic coding concepts and develop their computational thinking skills while bringing their own ideas to life. Scratch is a basic coding language that uses a ‘building block’ style coding to create animated stories, interactive games, simulations, and beautiful artwork.
