I am new to arduino and other electronic things, I want to try to control two lights on my room using it, I made this a sketch oh how I think the circuit would go, can someone with more experience tell me if it's going to work? or if there is any component I need to add?
Apologies for not posting a schematic, as I said this is my first project ever on electronics. This was the schematic that was generated, I hope it's good. About the microphone problem, the one I was intending on using would be one from my old headset, thought it would work, would it be hard to make an amplifier?
Also wanted to add just one more question if it's okay, if I want to add to the project a speaker and a sd card reader I would not have enough pins for it, is there a way to get more pins? maybe using and IC?
