Subjects get hot when light waves stimulate the valence electrons, and usually electric currents result in heat. I am wondering what the connection is between the electrons and the vibration of the atoms. Thank you for your time.

In case of a metal, it is the conduction electrons, not valence. If there is a current, there is a resistance. The resistance is given by collisions of the electrons with the positive ions of the atoms. This leads to vibrations. Some of the heat ends up in the electrons though since their temperature will be higher too.
