kids can learn the basics behind how the electronic circuits of an alarm system operate. The clock comes with easy-to-follow instructions on how and where to attach the different wires and place and attach its different components. And once complete you'll have assembled your own alarm-sounding siren with blinking LED lights. Disconnect different wires to turn off the LED lights or the motor's spinning feature of the alarm's siren. Further instructions are provided about the basic connections in the instructions guide.
Two AA batteries are required but not included.
