Hi all,

I have a device that produces PWM signal of 3.3V logic level. Does anyone know how to convert 3.3V logic level to 5V logic level using simple method? Please help me. Thanks.

There are devices designed for just that.

Try a Google or eBay search for 'logic level converter'

Also, an Arduino digital pin will recognise a 3.3 volt signal as HIGH, so you can just use it directly, ensuring that the grounds between the devices are tied together.
