Welcome! Broadcast blocks send a “message” to other sprites, which When I Recieve blocks, do something when they get that message For example you can put this on Sprite1

when this sprite clicked
say [Hello!] for (2) secs
broadcast [hi v]

and this on Sprite2 (you need to create this sprite)

when I receive [hi v]
say [What's up?] for (2) secs

so when you click on sprite1 it will say hello, then send a message to sprite2 to say What's up! Hope this helps!

The broadcast block is a way to communicate between two or more sprites. The Broadcast blocks will, as it says, broadcast a message, and any sprite or backdrop that contains a

when I receive [The Message That You Broadcasted v]

Will play whatever is stacked underneath the the

when I receive [ v]

is started.
The broadcast and wait block

broadcast [ v] and wait :: events

Simply waits until all of the When I Receive blocks are finished running before continuing on.
