Word Block TypesThe Scratch programming language is made up of different types of blocks, eachrepresented by a different shape.Hat BlocksHat Blocks are used to start a program. They have a rounded top so that otherblocks can only be attached under them.Stack BlocksStack Blocks perform the main commands in a program. They’re the blocks thatcan make the motors move and the lights light up!C BlocksC Blocks are C-shaped blocks. They’re placed between the beginning and theend of the loop or check whether a condition is “true.” All of the C Blocks can befound in the Control category.Reporter BlocksReporter Blocks hold values, which be a number or a string. Among other things,they can hold a sensor reading or store the value of a variable.Boolean BlocksBoolean Blocks are conditions that can either be true or false. They’re usedtogether with C Blocks to form the logic of a program.2LEGO, the LEGO logo, the minifigure, DUPLO, the SPIKE logo, MINDSTORMS and the MINDSTORMS logo aretrademarks and/or copyrights of the LEGO Group, 2020 The LEGO Group.

Cap BlocksCap Blocks are used to end scripts. They’re shaped with a notch at the top and aflat bottom so that you can’t place any blocks below them. There are two CapBlocks, both which can be found in the Control category.Block StacksA block stack is a number of blocks that have been put together.3LEGO, the LEGO logo, the minifigure, DUPLO, the SPIKE logo, MINDSTORMS and the MINDSTORMS logo aretrademarks and/or copyrights of the LEGO Group, 2020 The LEGO Group.

Word Block DescriptionMotor BlocksMotor Blocks either make the motors run or get information from the motors. The MotorBlocks category contains the most common Motor Blocks.Runs one motor clockwise orcounterclockwise for a specifiednumber of rotations, seconds, ordegrees.Run Motor for DurationThe motor speed is set by the SetSpeed Block. The default speed is75%.Run Motor for Duration at SpeedRuns one motor for a specifiednumber of rotations, seconds, ordegrees at a specified speed. Anegative speed value runs the motorcounterclockwise.Start MotorRuns one motor clockwise orcounterclockwise forever.The motor speed is set by the SetSpeed Block. The default speed is75%.4LEGO, the LEGO logo, the minifigure, DUPLO, the SPIKE logo, MINDSTORMS and the MINDSTORMS logo aretrademarks and/or copyrights of the LEGO Group, 2020 The LEGO Group. All rights reserved

Stop MotorStops one motor from running. Themotor will brake so that it quicklycomes to a complete stop. Themotor will not hold its position onceit has stopped.Set Motor SpeedSets the speed of one or moremotors. The speed range is -100 to100. Negative values will reversethe direction of the motor. If thespeed hasn’t been specified, thedefault value is 75%.Set Motor Position at StopSets the action that the motor willperform when its current commandcompletes. It can be set to eitherfloat or actively hold position whenthe motor stops.Set Motor Position at SpeedStarts running a motor at thespecified speed until the motor istold to do something else or theprogram stops. A negative speedvalue runs the motorcounterclockwise.Runs a motor at a specifiedpercentage of power until themotor is told to do something elseor the program stops. Unlike theblocks that use the speedparameter, which regulates thepower of the motor in order tomaintain a specified speed, thisblock will keep the power levelconstant without regulation. Anegative power value runs themotor counterclockwise.Start Motor at Power5LEGO, the LEGO logo, the minifigure, DUPLO, the SPIKE logo, MINDSTORMS and the MINDSTORMS logo aretrademarks and/or copyrights of the LEGO Group, 2020 The LEGO Group. All rights reserved

Reset Motor Degrees CountedResets the degree count of amotor to “0.” A motor’s degreecount is equal to the motor’srelative position from where itstarted. The degree count is “0”whenever a program starts, or amotor is connected to an EV3Brick. Turning the motor clockwiseincreases the count, while turningcounterclockwise decreases thecount.Motor Degrees CountedReturns the number of degrees amotor has turned. The degreecount is set to “0” when theprogram starts or is reset using theReset Degrees Counted Block.Turning the motor clockwiseincreases the count, while turningcounterclockwise decreases thecount.Motor SpeedReports the current speed of themotor. The value given is themotor’s actual speed, not thespeed set by the Set Speed Block.6LEGO, the LEGO logo, the minifigure, DUPLO, the SPIKE logo, MINDSTORMS and the MINDSTORMS logo aretrademarks and/or copyrights of the LEGO Group, 2020 The LEGO Group.

For example, ifthe input is “LEGO,” theblock returns “4.”ModReturns the remainder of thedivision when the first valueis divided by the secondvalue.For example, when 10 is thefirst input and 3 is thesecond, the block will report1 because 10 divided by 3gives a remainder of 1.Negative numbers behave alittle differently because aremainder must always bepositive (e.g., -10 mod 3equals 2, not -1 because youhave to multiply 3 by -4 tohave any remainder at all).Rounds the given number tothe nearest integer. If followsthe standard rules of .5 orhigher are rounded up,whereas decimals of lessthan .5 are rounded down.Round30LEGO, the LEGO logo, the minifigure, DUPLO, the SPIKE logo, MINDSTORMS and the MINDSTORMS logo aretrademarks and/or copyrights of the LEGO Group, 2020 The LEGO Group.
