okay, here’s the hard part… the right programing to make it look like T8 lamps…
this is how far i have gone with the arduino. I’m using Arduino duemilanove. i will need to make 4 blinking Led strings so for prototype i use 4 LED. I’m programing only one of them, and that’s quite hard to make it realistic enough…
