Home Automation through Cellphone Keying (H.A.C.K)

I always wanted to control my lights and other appliances in my room remotely while I'm somewhere else. Many a times I forget to switch off the fan or AC in my room and then I have to go back and switch it off. I always wondered how cool it would be if I could control my appliances through something like my cellphone (which I never forget to take). Well now I can see that dream right in front of me. Yes, its yet another hobby project by Kaushani and me. Its the 'Home Automation through Cellphone Keying(H.A.C.K)' .
