## Article

In today's video I will finally complete my Arduino based wired light controller. I decided, since I have plenty of inputs/output pins on the mega, I would use the same Arduino to not only control the relays that you can connect to your home lighting, but also add inputs for physical buttons that you can press in order to control those relays, or any other functionality you want in your smart house. That way you can have a dedicated, wired light controllers for all the lights in your house.
