Описание
The HEE-HAW Siren circuit uses two 555's to produce an up-down wailing sound. The first 555 is wired as a low-frequency oscillator to control the VOLTAGE CONTROL pin 5 of the second 555. The voltage shift on pin 5 causes the frequency of the second oscillator to rise and fall. This circuit is recommended for students and hobbyists as it teaches the basic concept of 555 Timer Circuits. It is a very interesting circuit and fun to make,Children as well as adults can learn very much from this circuit
