Hi everyone,
I am having a silly doubt,how can i use transistor to boost up the voltage.Because Arduino only supplies and output of 5v,what if I want to get an output of 10v or some-other voltage.Please let me know this as fast as possible.
Cheers

Have a look here, as an example. The transistor doesn't actually boost the voltage; rather it is used to control a higher voltage which must be supplied from another source.
For a BJT transistor the common-emitter configuration is a voltage and current amplifier, and is always
used for switching.
For MOSFETs you have to ensure the device is "logic-level" (works from 5V gate voltage),
and use common-source circuit (again voltage and current gain and how to use the device as
a switch).
The base in a BJT needs a resistor in series as the base-emitter voltage is restricted to about 0.6 -- 0.8V
or so. MOSFET gates need the full 5V but a low-value resistor will protect the arduino from current
spikes (MOSFET gates are highly capacitive load).
What are you trying to do?
