Hello instructibles!! I just made something really really cool. Its not quite mind reading but it sure is close! I have made an arduino powered eeg machine, also known as Electroencephalography machine. Now normaly these will cost you lots of money and are hard to understand without a degree in neuro science, but this arduino version is much cheaper and easier! So you might be asking… What does it do? In short it reads brainwaves that are created by your brain. This allows us to tell how much a person is paying attention or if he/she is deppressed or in an emotional state.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
