Hi there, I want to find out the direction of my house, but I still confuse how to use the compass. I don't know if the direction of the house based on the direction of the compass when I hold it facing into the front door or facing out of the front door. And then after I figure out the center of the house, how can I find the eight direction of the house and each individual room. If my house has a protruding part as a garage, so it has a L shape, do I need to count this part to calculate the center of the house? Thank you for any ideas or suggestion.
