Load up the Arduino with mind flex code for serial data out

Download and install the Arduino Brain Library — it’s available here. Open the BrainSerialOutexample and upload it to your board. (You may need to disconnect the RX pin during the upload.) The example code looks like this:

1. #include
3. // Set up the brain parser, pass it the hardware serial object you want to listen on.
4. Brain brain(Serial);
6. void setup() {
7.         // Start the hardware serial.
8.         Serial.begin(9600);
9. }
11. void loop() {
12.         // Expect packets about once per second.
13.         // The .readCSV() function returns a string (well, char*) listing the most recent brain data, in the following format:
14.         // "signal strength, attention, meditation, delta, theta, low alpha, high alpha, low beta, high beta, low gamma, high gamma"   
15.         if (brain.update()) {
16.                 Serial.println(brain.readCSV());
17.         }
18. }
