Here I made a smart AC plug using an arduino pro mini .We can on and off any AC device using this smart ac plug via android mobile. We can control it through our voice and by tapping on the screen by connecting the mobile to the ac plug through bluetooth. It's main advantage is it is not need to put inside the switch board it only need to plug in to switch board socket and connect devices like table fan, table lamp etc... This circuit can also use inside the switch board.
Here I'am showing how to make a arduino light seeking(follower) robot . Made using arduino pro mini it's very cheap I ally used 7$ (450 Indian rupee) to make this robot. This robot can find the door of the house by following light.
This is my robot for many purposes ,made using arduino and some other sensors. This robot can function as obstacle avoider, bluetooth controlled robot etc. it sense fire ,smoke,gas and any of them detected it make alarm sound. We can use this robot in home for security and use as pet.
