hey guys, i was sittin on my patio this afternoon drinkin a beer when sudden inspiration hit me. i thought it would be cool if my beer lit up when i set it on my glass table. i know i how to wire the LEDs, resistor, transistor and photocell but the problem is the glass is tinted or smoked. so light under the table is already reduced. i would like the photocell to remain off until the beer or cup covers it completely. my questions are.......
what size transistor should i use?
what size resistors?
and what size photocell?
i will be using 5 LEDs wired parallel
if you have any questions please ask. THANKS!!
