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.
All of the blocks in EdScratch are arranged into one of the nine different block categories in the block pallet.
