Don't finish your next Arduino project without adding a tiny TFT screen that can really add value (or that Wow Factor!). It's really easy to display silkysmooth scrolling (or static) information, instructions or error messages to your users or yourself. Best of all, the scrolling is all done by the hardware, not your Arduino code.

Available in both I2C and SPI formats I've used the I2C (TwinWire) version here but both are identical in capabilities. Two libraries were used (not at the same time), one from Adafruit and one from Greiman, both giving us very different functions.

And just to add to the mix I've added a new function to the Adafruit library to allow vertical hardware scrolling (but do watch the demo for a better version using the Greiman library).

At this price, they are almost giving the screens away so let's see what one can do.
