Abstract: Many systems involve some type of time keeping. By using 555 integrated circuit in astable state it is easy to design and make accurate and cheap timing circuit (e.g., alarm circuit, counting circuit, sensing circuit, etc.) The working principle of this 555 IC in astable state is supported by the following formulae: Timing period, Timing=(R1+2R2) C/1.44.
