    with the use of a transformer, bridge rectifier, and a voltage regulator (+ a few other components, such as a fuse, etc.)..... or buy a wall wart that will give you the proper voltage output that you need.... much easier and safer for beginners.....

    As BMorse said, "wall warts" or plug supplies are a great way for beginners to get a safe and inexpensive power supply started. Many are not regulated. If you find one that's rated for 9v-12v at 500mA to 1A, you can add a couple of capacitors and a 7805 fixed voltage regulator with a heat sink attached to make a very cheap 5v regulated supply. It won't be terribly efficient, but it will work.

    Hello,

    I moved the post to the home work help.

    I got this in an e-mail:

    I do not answer in e-mails.

    Here is a page of the EDUCYPEDIA on powersupplies:

    http://www.educypedia.be/electronics/circuitssupplies.htm

    There you will find a lot of information in the links.

    As it is home work, can you show us what your plan is?
