A simple LED torch would light up 3 white LED from 6 volts supply in case of emergency or in darkness. It is quite light-weight and handy, thus, can be used [[wysiwyg_imageupload::]]while traveling in train or in bus. Here we have used CD4049 IC which is a hex inverting buffer CMOS chipCD4049 contains six inverter gates in one package as shown in diagram. In this, pin 3 is input and 2 is for output. For first gate similarly pin 5 is input and pin 4 is output for second gate similarly we have four more gates. Pin1 1 is for supply voltage and pin 8 is connected to ground. Pin 13 and 16 are unused. The circuit is based on NOT gate CD4049 IC and utilizing 3 gates of NOT gate IC.
