Emotive BCI OSC(Solved)

[Doody02]

Greetings, I've tried to control the LED in arduino uno with using emotive epoc x and data stream on BCI OSC.

I followed this link

https://github.com/Emotiv/opensoundcontrol/tree/master/examples/EmotivOSC_Adruino

But the light won't work , am sure that I followed the instructions as this link above, would you kindly please advise about the arduiono uno code .

here is the pic above I uploaded the structure .

I tried the Arduino uno code in the link and it didnt work so I tried this ;

define LS 2 // left sensor

define RS 3 // right sensor

define LM1 5 // left motor M1a

define LM2 4 // left motor M2b

define RM1 7 // right motor M2a

define RM2 6 // right motor M2b

void setup() { pinMode(LS, INPUT); pinMode(RS, INPUT); pinMode(LM1, OUTPUT); pinMode(LM2, OUTPUT); pinMode(RM1, OUTPUT); pinMode(RM2, OUTPUT); } void loop() { if(!digitalRead(LS) && !digitalRead(RS)) // Move Forward on line { digitalWrite(LM1, HIGH); digitalWrite(LM2, LOW); digitalWrite(RM1, HIGH); digitalWrite(RM2, LOW); } if(digitalRead(LS) && !digitalRead(RS)) // Turn left by rotationg left motor in backward direction and right ones in forward digitalWrite(LM1, LOW); digitalWrite(LM2, HIGH); digitalWrite(RM1, HIGH); digitalWrite(RM2, LOW); } if(!digitalRead(LS) && digitalRead(RS)) // Turn right by rotating right motor in backward direction and left ones in forward digitalWrite(LM1, HIGH); digitalWrite(LM2, LOW); digitalWrite(RM1, LOW); digitalWrite(RM2, HIGH); }

if(digitalRead(LS)&& digitalRead(RS)) // Finish line, stop both motors { digitalWrite(LM1, LOW); digitalWrite(LM2, LOW); digitalWrite(RM1, LOW); digitalWrite(RM2, LOW); } }

@Doody02 i don't see their code above connect to your machine(Emotiv BCI). can you send me that part?

[Doody02]

@hoangphamemotiv of course I will upload it now

[hoangphamemotiv]

@Doody02 that is about Emotiv BCI config. how about your Arduino code to connect to your PC via Ethernet or Wifi?

@Doody02 seem you missed to add code of controling LED in the processMC() function. and to use Mental Commands detections, you need to training detection (like: push, pull, right, left....) and wearing your headset to receive detection data. note: Mental commands is different with Motion. Document of Emotiv detections, you can find from Emotiv BCI app

[Doody02]

@hoangphamemotiv Do u have by any chance the code for controlling LED , also I do use the sensor while testing knowing that I have train all of ( push , pull , right , left ) with 2 train each . I do take my caution knowing that motion really do Affect the brain wave and change its pattern.

If my only problem is the LED code would you kindly please help me with this matter .

Thanks in advanced ....

[hoangphamemotiv]

you need adding LED code in which detection you want to control: for example: void processMC(OSCMessage &msg, int addrOffset) { if(msg.match("/neutral", addrOffset)) { Serial.print("MC - Neutral: "); digitalWrite(LM1, LOW); digitalWrite(LM2, LOW); } else if(msg.match("/push", addrOffset)) { Serial.print("MC - Push: "); digitalWrite(LM1, HIGH); } else if(msg.match("/pull", addrOffset)) { Serial.print("MC - Pull: "); digitalWrite(LM2, HIGH); }

[Doody02]

@hoangphamemotiv so the code will look like this right , but i still get the error of compile whenever i put it diffrent error appears .

you have 2 functions with the same name: processMC

[Doody02]

could it be the BCI OSC .

[hoangphamemotiv]

@Doody02 . i think you can try yourself step by step. the first step you should make sure you connected success your board with wifi/Ethernet. i suggest you connect via Ethernet, it is easier. after that you can connect your board to PC via serial port for debuging to see if data sent to your board.

back to your code. i think you should not use ip: byte ip[] = { 192, 168, 1, 1 };

[Doody02]

1- the board is successfully connected via ethernet . 2- the serial port is connected as well . 3- I deleted the byte ip + {192 , 168 ,1 ,1 }

[Doody02]

would please kindly advise , i am sorry for asking too much I just wanna know where is the flow .

deeply thankful for the assets.

[Doody02]

thank you so much for the help , it worked with Ethernet perfectly it turns out all i need is the IP from the switch I had .
