How does the addition of the bill of rights to the constitution to limit the power of the federal government?

The Bill of Rights was created to give the Americans to have well rights and keep the federal government in it's gives you the right to a fair trial, you can not be searched without a warrant, the government can not force you to house soliders, and the individual branches of government CAN NOT do what the constitution does not allow. Such as the president can not make a law. Only the Legislative Branch can.
