grandmasteralok Posted October 9, 2012 Report Share Posted October 9, 2012 Hi guys,It's been a while...I have been trying to build a 300-pc. LED lighting unit... It's a simple project consisting of 300 pieces of 5mm superbright white LED's... I was able to make them light up using 4 pcs. of AA NiMH batteries, which then I switched to an 8-pc. AA power source for prolonged sustained output... What put me to a halt is the question of how to make them dim altogether... I heard about potentiometers but I don't know how to use them, I mean would I still need the resistor for each LED??? One more thing... Since the potentiometer has 3 pins, which one will I connect to either + or - leg of the LED???It would be best if you could provide me a diagram and parts listing, especially the potentiometer or any dimming piece...By the way, I don't have access to any chip-programming device so basically I am doing an non-programming project...I plan to use 8-10 pcs. of AA NiMH batteries as power source or a 12v AC-DC converter...Your help is very much appreciated...
