Arduino CO Monitor Using MQ-7 Sensor : 8 Steps (with ...

I have made a connection as shown in the circuit. And I have uploaded the same code. But, despite that the values of voltage is V and V(not V and 5 V(measured by a multimeter between Vcc and GND of MQ-7) ). I have tried changing values of 1k ohm resistor and have removed the connection as shown in step 2. B0139 is the transistor.
