3 Amazing BRAIN / MIND Control Projects Lights LedStrip LED With Arduino and Neurosky

Setting Up the Connections 1 (1)

Have you ever wanted to turn the lights ON or OFF just by thinking about it? Or do you want to know how stressed you are by looking at the color of a RGB led? While now you can by following this Instructables!

To get a feeling for what we are going to make today I recommend you first watch the youtube video above for a short Demonstration!

This Instructables actually exists of three projects that all use brain control. Yes that are three for the price of one!

The first project is the MoodLight. This project uses a RGB led to show your mental status. When you are very relaxed it is green, but when you become stressed it will turn red. This project needs the following:

1x Arduino Uno or Nano

1x Neurosky Mindwave headset

1x RGB common annode Led

3x N channel Mosfet

1x Visual Studio 2017

The second project is the Relay project. This project uses a Relay to turn a led ON or OFF just by thinking about it! Because it uses a Relay you can hook everything up to it. Your Lights, Your TV or even your coffee machine! For this project we need:

1x Arduino Uno or Nano

1x Neurosky Mindwave headset

1x 5v Relay

1x BC 547 Transistor

1x 5V LED

1x Visual Studio 2017

The third project is the Led Strip project. This project uses a WS2812 individueel addressable RGB Led Strip which will turn on more Led’s and turn more Red how more stressed you become. For this project we need the following

1x Arduino Uno or Nano

1x Neurosky Mindwave headset

1x WSD2812 RGB Led Strip

1x Visual Studio 2017

This project uses the Mindwave RF version. You can buy it for example here:


So lets get Started!

Step 1: Setting Up the Connections

Setting Up the Connections 1 (1)

For all three projects we first need to setup the connection. We will do this with a little program called ThinkGearConnector.

To get started download all the code and drivers from the Github repository below:


Also download the Mindwave pairing installer from here:



After downloading the Github repository unzip the ArduMind.zip file.

After that open the ArduMind folder and go to the Drivers folder.

Now plug in the Mind Wave reciever into your computer.

After that double click on the SETUP.EXE and install it.


After having installed the Drivers unzip the MindWave.zip file and run the installer still with the headset plugged in.


After having established the connection we can install the ThinkGearConnector.

From the ArduMind folder go to ThinkGear Connector > win32 and double click the ThinkGear Connector.exe with the headset still plugged in.

Getting the COM port

While the headset is still plugged in we need to get the comport of the MindWave headset. This is needed for step 2.

To get the COM port:

1 press windows key + x and select device manager

2 go to ports(COM&LPT)

3 then look for MindWave USB Adapter

By this name you can find the COM port. If you look at the image above you can see my COM port is COM8

Step 2: Setting Up Visual Studio

Setting Up Visual Studio (1)Now we can start with the Fun part!

First of all select which of the three projects you want: Moodlight, Led Strip or Relay.

I am going to choose the Relay project.

After having selected the project go to the ArduMind folder and then to: 3 Mind Control Projects > Relay Control > RelayControl C#.

Now double click on the HelloEEG.sln to open it in Visual Studio.

In the solution explorer on the right click on the HelloEEG.cs file.

In here search for line 30 and change:

connector.ConnectScan(“COM3”); to the comport we found in step 1.

So for me:


After this we can start with the hardware. But keep Visual Studio open because we will need it again!

Also unplug the Mindwave headset

Step 3: The MoodLight

For the Moodlight project we first have to make the electronics. You can find the schematic in the image above ^.

Make sure you are using a Common Annode LED.

For the mosfets I am using the RFZ44N.

After having made the electronics we need to upload the Code to the Arduino.

The code can be found in the ArduMind folder. Then go to 3 Mind Control Projects > Moodlight > Moodlight Arduino.

Now simply connect the Arduino and click the Upload button.
