closed after charging the capacitor C1 to a C1-powered, so IC1 pulse oscillation source composed only been a while (more than ten seconds) will stop the vibration. But it is the first oscillation frequency from high to low. Pulse counting, decoding so constituted by the IC2 and display driver driven ten LED, then also with the pulse IC, output and to slow down after another to stop the flashing.
