?Mind Controlled devices? this project is totally based on the mind waves that is alpha waves. That mind waves has frequency in between 7.5Hz to 12.5Hz.All biological system is operates in same frequency range. Now this thing will have many advantages to control many different devices like AC or DC devices. This will be very use full for many fields like in defense, medical uses, industry, also in daily life. This project will increase the human limits. It also make life easy. Mind Controlled devices will consist of EEG electrodes some instrumental amplifies microcontroller boards through the instrumental amplifier we will trying to amplify the alpha signals which is read able to the microcontroller board.
