		<description><![CDATA[OBJECTIVE Timer IC 555 is versatile general-purpose linear integrated circuits and is thus the most widely used one. It is indeed a favourite with hobbyists. It is mostly used either as a monostable or an astable multivibrator. In this project activity, we shall present some modified circuits for monostable and astable operation of timer IC [...]]]></description>
