I need someone with a good understanding of electronics to provide me with a solution, rough background:
external power source provides a power to filament lamps and an arduino board. the voltage of the power source is constant, use two digital pwm output pins on the arduino board to control the intensity of the brightness of both lamps using NPN transistors.
Forgot to mention some info:-
-Circuit diagram required (microprocessor may be represented as a block)
-both lamps are have 2.5 ohm resistance
-current supply up to 3amps, Voltage supply is 5volts, each with 2 ohm resistance, this info may be useful incase you need a resistor

Dear Hiring Manager, I can perfectly do the desired job for you. I will provide you the code + circuit diagram so that you can build the prototype on your side. Regards.
hi sir i am an expert electrical engineer I can do it for you I have almost 4 years of experience in this field. I have done a number of projects on arduino I am waiting for your reply to start regards
Previously i had faced such problem while making robot where DC Motor were used instead of lamp. So i can solve this with what is given. If you need further optimization i will also help you with that.
