NE555 Generator.

Friends! I decided to create a rectangular pulse generator. For this purpose, the world- famous chip with the abbreviation NE555 was required . This is a classic of the circuit modeling genre . I did a lot of projects using this timer and I was interested . And You? Have you worked with this timer? What did You do ? I even received ultrasonic vibrations whose frequency exceeds the human hearing sensitivity limit of more than 20 kHz. It was interesting))) See how the sound changes with increasing frequency. Sincerely, Yuri Kovalenok.
