Hi just got my arduino Mega2560 and one of these today Arduino compatible IIC/I2C/TWI YwRobot Serial LCD 1602 16x2 Module | eBay
I also got a breadboard and some wires for connecting stuff. So you can imagine the scene, excited full of beans blah blah(you know where this is going)
Anyway I plugged the LCD into abcd on my breadboard and then connected gnd to a +5v to b pin 4 to c and pin 5 to d as per the instructions but absolutely nothing happens, so I started playing around and discovered that if i take the pin out of +5v then the arduino powers up and if i put it back in the arduino turns off and all the lights go off, so figured I was shorting the gnd and +5v so I moved some stuff around and fixed that, but still the lcd does not light up, I have swapped to another LCD(I bought 2) and that doesn't light up either.
I have done a bit of googling and also some youtube searches but I am obviously missing something(might be a brain), can anyone help?
Thanks
