I have the lynxmotion wireless PS2 controller and it won't connect to the receiver. The green light on the receiver is solid and the red light is blinking. On the controller, the red light is blinking and the green light isn't lit up at all. I uploaded two photos of my wiring.

This is the code I'm using, if that has anything to do with it. It's on the lynxmotion website here: http://www.lynxmotion.com/images/html/build035.htm

They are suppose to connect of you just supply 5V, whithout any more pins or code, so if they dosnt there are something wrong in the hardware ... sorry

As i am Swedish, you may laugh at my spelling and grammar, but please please don’t comment it if you understand what i mean

Would the wiring affect that at all? If it's getting power then it should connect regardless of its data connections to the board, right? So if it's getting power and not connecting, then it's probably a bad controller?

Oh. You said that exactly. Sorry.

It connected when I plugged it into my PS2.

Check your battery. Maybe you have enough power to lit the led but not enough to connect. Often a power problem.

Also check the jumper. Be sure that is is on 5V, not VS. The receiver needs 5 volts. If it has more or less, it may not connect properly.

Curiously enough, the only thing that went through the mind
of the bowl of petunias as it fell was "Oh no, not again."
