Fireworks Launcher

This project is designed to launch for 4 fireworks sequentially. The lamps are a standin for "resist wire" which gets very hot when a current is applied. The resist wire lights the fuses of the fireworks. The "burning" of the lamps is intentional. 

TODO:
Add an "arm" throw switch
Add a momentary switch in place of the clock signal.  This digital / analog conversion prooved difficult. Any thoughts would be appreciated.  The idea being too push the same button four times to light the fireworks.
