# Control Electronics with your Brain using NextMind ## Overview https://youtu.be/QE-HWeD2fJw ![](https://cdn-learn.adafruit.com/assets/assets/000/098/712/medium800/feather_nextmind1.jpg?1611065444) Use neural signals from your brain’s visual cortex to control electronics. This guide will show you how to use the **Nextmind** Dev Kit, **Unity** game development software, and an Adafruit **Feather** microcontroller board to control a servo motor with your mind & visual focus. This example project translates area of visual focus into the physical position of a servo with attached pointer, but it is just that – an example. You’ll likely think of a million more awesome applications after experimenting a bit. The Nextmind Dev Kit offers an unusually reliable method for converting neural activity to user input. The device's sensors measure tiny electrical signals from the visual cortex located at the back of the brain. So, it essentially reads what you’re visually focussing on. This may seem less magical compared to other brain-computer interfaces, but it seems to make the Nextmind much more practical, dependable than other brain-computer interfaces I've experimented with. ## What you’ll need - [Nextmind Dev Kit](https://www.next-mind.com/) - Windows or Mac computer w Bluetooth - "Craft stick" / tongue depressor (optional) ### Part: Feather M4 Express quantity: 1 Feather M0, QT Py, others should work as well [Feather M4 Express](https://www.adafruit.com/product/3857) ### Part: Micro Servo quantity: 1 SG92R [Micro Servo](https://www.adafruit.com/product/169) ### Part: Micro USB Cable quantity: 1 Connect Feather to your computer [Micro USB Cable](https://www.adafruit.com/product/592) ### Part: Hook-Up Wire quantity: 1 Set of 6 spools [Hook-Up Wire](https://www.adafruit.com/product/1311) ### Part: Half-size Breadboard quantity: 1 For Feather to servo connections [Half-size Breadboard](https://www.adafruit.com/product/64) ### Part: Wire Strippers quantity: 1 For makin' jumpers [Wire Strippers](https://www.adafruit.com/product/527) ### Part: Pocket Screwdriver quantity: 1 Install pointer on servo [Pocket Screwdriver](https://www.adafruit.com/product/3284) ### Part: Panavise Jr. quantity: 1 Optional way to hold servo during use [Panavise Jr.](https://www.adafruit.com/product/151) - [Next Page](https://learn.adafruit.com/control-electronics-with-your-brain-using-nextmind/nextmind-setup.md) ## Featured Products ### Adafruit Feather M4 Express - Featuring ATSAMD51 [Adafruit Feather M4 Express - Featuring ATSAMD51](https://www.adafruit.com/product/3857) It's what you've been waiting for, the Feather M4 Express featuring ATSAMD51.
