Hey guys, i decided to try and make this mood lamp:
http://tobe.nimio.info/led_mood_lamp.php
All the details regarding this project are at the same page.
I got it all together, i programmed the pic with the included hex file but i did use a different rgb led. I used this one: http://www.maplin.co.uk/Module.aspx?ModuleNo=35893&criteria=rgb led&doy=16m12
The problem is when i tried to use it, the led would come on but bbaaaaaarely on. Like just about visible at a few inches away. Then when i turn of the PSU the leds flash on briefly. I took my multimeter and measured the voltage coming out of the output pins of the pic and they measure in the millivolts (i think around 400 millivolts cant really remember) So i think that that is the problem as the voltage coming out of the pic should be at least .7 volts to turn on the transistors right? Also i used bc548 transistors. Anyone have any ideas or suggestions for me?
Thanks alot,
Greg
