I'm new to electronics but learning to built LED projects through trial, error and.. reading on the net. I am making sea tides related signs for the outdoor depicting tide level at a given location and time. To make it short I build lights made of plexiglass and red and blue LED's connected in series. Depending on the tide cycle those lights will show either a uniform red or blue color. This is working fine, but I understand that I buy, drill, glue and wire double the LED's I should if only I could use in some way RGB leds instead. I have googled many hours to find out if one can wire 4 leads RGB led's in serie but didn't get anything clear about that. Anybody can help ? Thanks in advance korg
