RFID Project

My first Arduino project is an RFID door unlocker for my home.  Below are the obstacles I have to overcome:

1.)  DONE Get the Arduino to read a tag (with an ID-20 reader) and compare it to stored tags in its EEPROM
2.)  DONE (bought one) Figure out how to build an H-BRIDGE
3.)  DONE Buy, take apart and run wires to the motor powered deadbolt
4.)  Solder the finished circuits to some boards
5.)  Install
