Hi all, I'm building a simple circuit to control a ceiling fan and light using a cheapo Chinese IR remote. I've adapted a sketch I found on 'tinternet and although a little tweaking is still needed it seems to work ok, except when first powered up nothing happens unless I press reset on the Arduino. Any ideas what might be causing this? Many thanks for any advise as usual. Regards, Bob.

const int RECV_PIN = 7;

const int A1Pin = 10; //Speed 1 relay
const int A2Pin = 11; //Speed 2 relay
const int A3Pin = 12; //Speed 3 relay
const int A4Pin = 6; //Spare output for later
const int A11Pin = 5; //Light relay
