    hi guys Im confused in this please i need help

    am going to use adruino board mega2650 to control brightness of LED light bulbs
    but am still thinking of how would I have an enough power supply to power 4 LED light bulbs that each one has input voltage of 90v ac to 290v ac, because I was thinking of using a regular battery 12v dc but i thought that wouldn't be enough and those batteries are dc voltage .

    any clarification or suggestions would be appreciated guys

    Personally I believe if you have to ask this type of question you should NOT be doing this project. Working with line voltages is NOT safe for unskilled users like yourself.

    Googling "arduino triac dimmer" will get you started on your path to learning. :)
