This easy-to-build project mimics the two-tone sounds of many ambulance services. The Kit comes complete with an 8 Ohm 0.25Watt speaker, and it is an ideal entry point into basic electronics. Students will find that by altering the values of the timing components they will change the sounds being produced. Applications include class room instruction, toys and alarm systems.
