Q. Could other noises be the trigger for this circuit? For example, a telephone ringing?
A. Hi Sam, Thanks for your question. Any short, sharp, loud sound would work but you could test other sounds as long as the source of the noise is in close proximity.

Q. Can you assemble the circuit on a non-solder breadboard?
A. Hi Naz, thank you for your question. Most of the components would fit apart from the relay. A PCB is supplied with the kit however.
