I am building a clock. I am a good artist/designer/woodworker...but not a very good electrician. I have built a clock with a train theme. Inside I have installed a quartz clock movement with a built-in trigger switch which turns on "train sounds" on the hour. The train sounds are created from a small circuit board kit powered by 2 "AA" batteries. I have also incorporated a momentary pushbutton switch to enable playing of the train sounds whenever I want to hear them. This all works great. The train sounds play 20 seconds and then shut off automatically.
I also installed flashing lights on this clock, on a R/R crossing sign, and on a couple of locomotives, etc. It is a flashing light kit, on a small pcb, which alternately flashes led's. It is powered by a 9 volt battery, and is turned on and off with a pushbutton switch.
Here is the problem I hope someone can help me with: I would like to have the flashing lights turn on at the same time as the train sounds, flash 20 seconds and then shut off. Will a capacitor combined with a resistor work to control this type of circuit? Also, can the trigger switch on the clock movement fire both circuits? Any advice would be greatly appreciated.
