If you are using the adapter in this link,http://www.ebay.com/itm/Wii-WiiChuck-Nunchuck-Adapter-Module-Board-for-Arduino-/351052353286?pt=LH_DefaultDomain_0&hash=item51bc59cf06 then you most likely have it plug into the arduino across pins A2 - A5. Please know that the controller needs 3.3V to work properly and NOT 5V. You may cause possible to the controller if it is powered by 5 volts. What I have done here is allowed the user to use pin A2 as ground, by setting the pin to LOW, and making pin A3 an input so the user can have a jumper to the 3.3V pin without harming the Arduino. **.begin(Vcc, Gnd)** Vcc: Set to ON if you are using the adapter AND the Arduino board you are using outputs 3.3V. (Like a Pro Micro or DUE) Vcc: Set to NEUTRAL if you are using your own wires and are not using pin A3 for power. (pin will be set to INPUT) Gnd: Set to OFF if you have the adapter in the pin A2, this will automatically set pin A2 to LOW. Otherwise leave empty, default is OFF */ //#include #include //WiiClassicControl Wii; #define ADDRESS 0x52 void sendByte(int data, int location) { Wire.beginTransmission(ADDRESS); Wire.write(location); Wire.write(data); Wire.endTransmission(); delay(10); } void setup() { //Wii.begin(NEUTRAL, OFF); // SEE ABOVE #ifdef DEBUG Serial.begin(115200); //pinMode(9, INPUT); #endif Wire.begin(); // transmit to device (byte)0x52 sendByte(0x55, 0xF0); sendByte(0x00, 0xFB); Wire.endTransmission (); } void loop() { #ifdef DEBUG unsigned long t = micros(); #endif Wire.requestFrom(ADDRESS, 6); //request data from wii classic /*Serial.print(Wire.read(), HEX);Serial.print(" "); Serial.print(Wire.read(), HEX);Serial.print(" "); Serial.print(Wire.read(), HEX);Serial.print(" "); Serial.print(Wire.read(), HEX);Serial.print(" "); Serial.print(Wire.read(), HEX);Serial.print(" "); Serial.print(Wire.read(), HEX);Serial.print(" "); sendByte(0x00, 0x00); Serial.println();*/ uint8_t i = 0; while(Wire.available()) { Joystick[0].data[i] = Wire.read(); i++; if (i > 5) break; } //detect if init is needed if (i < 6) { delay(100); sendByte(0x55, 0xF0); sendByte(0x00, 0xFB); #ifdef DEBUG Serial.println("Init!"); #endif delay(100); } else sendByte(0x00, 0x00); #ifdef DEBUG Serial.println(micros()-t); #endif /*for (uint8_t i = 0; i < 6; i++) { Joystick[0].data[i] = Wire.read(); } sendByte(0x00, 0x00); */ /*while (Wire.available ()) { // read byte as an integer if (cnt < 4) { status[cnt] = Wire.read(); } else { lastButtons[cnt-4] = buttons[cnt-4]; buttons[cnt-4] = Wire.read(); } cnt++; } if (cnt > 5) { WiiClassy::_sendByte(0x00, 0x00); cnt = 0; }*/ //Reference for this found here: http://wiibrew.org/wiki/Wiimote/Extension_Controllers/Classic_Controller // the lowest value is 0, and the highest value is 248. /*Serial.print("LSX: "); Serial.print(Wii.leftStickX()); Serial.print("| LSY: "); Serial.print(Wii.leftStickY()); Serial.print("| RSX: "); Serial.print(Wii.rightStickX()); Serial.print("| RSY: "); Serial.println(Wii.rightStickY()); Joystick[0].data[4] = Wii.leftStickX(); Joystick[0].data[5] = Wii.leftStickY(); Joystick[0].data[2] = Wii.rightStickX(); Joystick[0].data[3] = Wii.rightStickY(); Joystick[0].sendState();*/ uint8_t rightShoulderPressure = (Joystick[0].data[3] & (unsigned char)0x1f); //rightmost 5 bits uint8_t leftShoulderPressure = ((Joystick[0].data[2] & (unsigned char)0x60) >> 2) + ((Joystick[0].data[3] & (unsigned char)0xe0) >> 5); //'leftish' bits uint8_t leftStickX = (Joystick[0].data[0] & (unsigned char)0x3f); //rightmost 6 bits uint8_t leftStickY = (Joystick[0].data[1] & (unsigned char)0x3f); //rightmost 6 bits uint8_t rightStickX = ((Joystick[0].data[0] & (unsigned char)0xc0) >> 3) + ((Joystick[0].data[1] & (unsigned char)0xc0) >> 5) + ((Joystick[0].data[2] & (unsigned char)0x80) >> 7); //bits.
