Below is a demonstration of connecting a simple circuit. You can start with this simple circuit
as a practice before moving to other advanced circuits.
First of all, take out the components shown in below diagram from your amazing connection
kit. They may be packed in different bags. Then install them like the pictures shown.
It is now done! Insert 2pcs AA size batteries to the 3V battery compartment. Turn the
switch on. The circuit is connected and current can flow in the circuit. Then the bell will
ring!
