Nice job.

The I2C version displays offered on some of the asian sites have the option of 3v3 operation.

They have an extra chip to drive the LCD part, and I accidently got one and wondered why it wouldn't work on 5v, no matter how I set the contrast.

You are right about the price for such a simple device ...

You can put solder on the wires with your big tips and then just touch the wire to your connection and heat it from the top.

The solder will flow off the wire and on to the contacts.

Just make sure you clean the contacts and put a bit of flux on the contacts before you start.

Hi Inderpreet,

Nice!! Those LCD's are great. The serial interface helps too, since messing with HD44780 style displays uses up I/O..

I don't know why the pins are on such a small pitch however [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-8a992787-a620-45bc-af22-1264931de5f1/contentimage_5F00_1.png:16:16] There is plenty of space on the LCD for 2.54mm spacing! : )
