ok i have gotten all 3 strings to light up using the 5 volt as the dimming input so the wiring on the strings is now correct. this is the first time i have ever used and ardino and i am confused. i have placed the following files into the libraray file on the ardino, ds1307 cpp file, ds1307 o file, ds1307.h, timer1, but i dont know how to get them to compile. i read the part about restarting the ardino IDE but i dont know how to do that. my red blink button is blinking so there is something going on in there. also i dont know where to go into to do the setting of the timers on the dimmers. thanks in advance, hopefully i will get this thing up and running within the week so i can post some pics.
