Troubleshooting a Boost Converter Circuit

In summary: If you take the transistor out of the circuit, the voltmeter should read around 3 to 4 volts. If it doesn't, something is amiss.Check if the transistor still working. At low frequencies it might be cooked easily.Try it again with the transistor mounted on a heatsink, and at 10-15kHz frequency. You can use a small speaker to check if it is working.Even higher frequency would be better, but I doubt that the Arduino would be able to drive the transistor at that speed.In summary, the multimeter I am using says 0.36 volts, but the circuit I am using says it should boost 4 volts to 8 volts. The resistor between the Arduino uno and

and i put it between the transistor and capcitor.

The right way around ?

redraw you circuit
