The ICONIC 555!
Wikipedia describes “The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package.” We described it as the most used, most versatile, awesome chip you can find.
