NE555 - Car dome light dimmer.

This is car dome light dimmer with some cool and important features. Switch on the upper left corner of the circuit is car's door switch (ground), and the switch on the upper right corner is car's ignition switch on /off AAC position. (In the middle of the circuit is two switches that has nothing to do with this, just have to put those there, cause this program wired this circuit wrong way without those.) Features. (About times...) Without ACC connected ---- Delay when door closes - 8 Sec. Delay if door left open - 2:45 Min. ACC connected ---- Delay when door closes - 2 Sec. Delay if door left open - 50 Sec. Other things ---- When you turn ACC to off position and your door is closed, lights will turn on about 8 Sec. Have fun... ;D
