555 Timer Circuits

The 555 Timer IC is a popular 8-pin Integrated circuit chip that can be used in a variety of timing and pulse generation applications. The IC can operate in three different modes such as Astable, Monotstable and Bistable, because of which it can be adapted into many types of circuit designs like time delay circuits, pulse generation circuit, oscillator circuit and much more. The below list from Circuit Digest consists of a huge collection of 555 Timer circuits with neat circuit diagram and practical DIY hardware explanation enabling you build your own 555 Timer projects.
