IoT based Smart Electric Switch Controller using Old PC DVD writer
This project can control your home appliences(Turn ON/OFF) by using voice commands. For this system I used old DVD
writer of my PC the benifit of using this mechanism is that you don'nt need to make any additional wiring in your electric switch board (like relay module connecting relay module in the board) this sytem can be directly attach
to the electric board externaly.
Due to the small size of this DVD slider it can control only 3 buttons but if you are using stepper motor like 28BYJ stepper motor then you can easily control buttons upto 7-8
