Hello, Im wanting to hook up some sort of gaget that would show me a red LED light if the garage is open. I found the picture on the net here and had a few questions about how I could change a few things.
1) First, Im not sure how bright the LED light is but I dont want a light that would light up a dark room I just want a suttle/dim red LED light so what size LED would I be looking for and if I changed the size would I have to chang the size of the resistor?
2) Second, If I wanted to have a green light to show that the door is all the way closed how could I wire it in to the schematic.
3) Third and final question, If I wanted to wire a second red LED how could I wire it into the schematic. Thanks.....
