Serial Monitor is not returning values at all,not even zero. These are the steps.
Arduino is communicating with the computer and is running example programs but not with the Classic Wii Controller. What am I doing wrong?
Oh, I am using the Arduino Uno
What am I doing wrong?
Not telling us what you are doing. There are quite a few things you could be doing wrong, from copying and pasting your code to wiring it wrong.....Please post pictures, schematics and code.
Sorry about that. Here are the codes I used.
/*
WiiClassic Test Code
This code prints the current controller status to the serial port.
Button pressed calls poll whether the button was pressed since the last update call.
as a result, it will just briefly print the last button pressed once.

What is showing up in the serial monitor? Can we see a picture and schematic of your hardware?
Also, I can't get the code to communicate with my Classic Wii Controller. After downloading my codes sucessfully, when I press the joysticks/buttons on the controller, nothing moves ad there is no light change on the victors. Please help. My competition is next Saturday!
Maybe your classic controller was burned by powering it on 5v while its desigined for 3.3v. try with another controller, and connect it to 3.3v. because I2C is 5V, its recomended to use a logic level converter or 2 voltage dividers and diodes. you can made this like:
arduino A4 or A5--10K-|- 5.6K--Gnd
| |
|----<diode<--wiimote
Repeat this two times for the two wires.
I don't believe the wiimote is grounded. Before following the above advice, add the following function to the end of your pde file and call it at the very beginning of setup()
// Uses port C (analog in) pins as ground for Nunchuck
static void nunchuck_setpowerpins()
{
#define gndpin PORTC2
DDRC |= _BV(gndpin);
PORTC &=~ _BV(gndpin);
delay(100); // wait for things to stabilize
}
How would you call it at the begining of setup() ? (I'm really new to arduino)
after the line
void setup(){
and before the line
wire.begin
just add the line:
nunchuck_setpowerpins();
