So I've hacked a mindflex toy device to read the serial data using frontier nerds instructions. I wanted to know how I could use the serial data to turn on and off a 3-6V fan motor when the Attention and Meditation eSense values are detected? The only help online uses an HC-05 Bluetooth module, which I don't have, to power a much higher voltage fan. Is there no way I can program the arduino to just turn the power on when concentrating or is it much more complicated than that?
I've attached a screenshot of the serial monitor displaying the raw EEG data when the headset is on

The code:
// Arduino Brain Library - Brain Serial Test
// Description: Grabs brain data from the serial RX pin and sends CSV out over the TX pin (Half duplex.)
// More info: https://github.com/kitschpatrol/Arduino-Brain-Library
// Author: Eric Mika, 2010 revised in 2014
#include <Brain.h>
// Set up the brain parser, pass it the hardware serial object you want to listen on.
Brain brain(Serial);
void setup() {
// Start the hardware serial.
Serial.begin(9600);
}
void loop() {
// Expect packets about once per second.
// The .readCSV() function returns a string (well, char*) listing the most recent brain data, in the following format:
// "signal strength, attention, meditation, delta, theta, low alpha, high alpha, low beta, high beta, low gamma, high gamma"
if (brain.update()) {
Serial.println(brain.readErrors());
Serial.println(brain.readCSV());
}
}
Any help would be much appreciated as I am very much a beginner out of my depth, thanks!
