I bought a sensor shield from the eBay shop which had a compatibility issue, and you very graciously helped me out with a great deal on a new Arduino board.
The new board arrived today, so I hooked it up to do a test but couldn't get the board to see the I2C LCD screen on the other end.
After much head-scratching, scanning and resetting, I finally worked out where the problem lay by looking at one of the photos on the forum.
The issue was that the sensor shield needed two jumpers connected (on the block of pins labelled IIC / COM). I found a couple from an old PC motherboard which seem to do the job and everything sprung to life
Could I suggest that the board should either be supplied with a pair of suitable jumpers, or with a note to mention that they're needed.
It's possibly something that should be obvious, but it's the first time I've used a shield with my board so it's all new territory to me
Anyway. This is meant as constructive criticism, I've had superb service from you so I'm not moaning. Now I've found you guys, I'll be coming back for more things in the future.
