Awesome response by @Zwazel for code connection, but remember that you can connect
via the visual interface by:
1. Going to the node that emits the signal
2. Click Node section
3. Choose the signal and click connect
4. Now choose the node to be connected and func name

Example 2: custom signal godot

signal my_signal


func _ready():
    emit_signal("my_signal")
