In this circuit using 4049, pins 6+7 and 9+10 remains unused, do i need to connect them to any other component. Till now, i kept those pins disconnected but the circuit is not working.

Welcome to EP!
Ground 7 and 9. Leave 6 and 10 unconnected.
Unused inputs of CMOS circuits should never be left floating.

Do i need to connect any resistors between the inputs and ground, if so what will be their value. Thanks in advance.
