Michal Gluszczak Studio 7 Slubica Dobra 2 96 311 Skuly POLAND studio7@kki.net.pl http://www.kki.net.pl/studio7 I have just purchased PIC START PLUS package from Microchip. I hoped that I will be able to start my first projects in few hours, but foud that my electronic experience was not enough. Until now I have build many machines controlled by simple CMOS logic. I hoped Microchip will include few step by step projects with included 16c84 for absolute beginners in microcontroller field, but I did not find it. Please guide me a little bit in my first days. As for sound coupling when I do not see your diagram I could advice to try with different values of R L C on attached "uncouple JPG. I think the most important would be to apply c around 1-100 uF and r 1-300 ohm depending on power consumption. By the way I am 32 Y.O. , live in a country by choice. I am the producer of beeswax candles.
