Scratch Event Blocks

Scratch Event Blocks are a fundamental part of programming in Scratch, a popular educational platform developed by MIT. These blocks allow users to trigger specific actions when certain events occur, such as mouse clicks or keyboard presses. Event blocks come in three main categories: sensing, motion, and control. Sensing event blocks detect user input, like the sound sensor detecting a noise or the light sensor measuring brightness. Motion event blocks respond to physical movements, like the movement of a sprite on the screen. Control event blocks manage program flow, such as setting flags or creating loops. For instance, a sensing block might read "when flag clicked" and perform an action when the user clicks a flag. A motion block could say "when green flag clicked" and make a sprite move when the user clicks the green flag.
