Female headers (these come in strips of 40).One or more unpopulated protoshields, both for Uno and Mega/Due.A solderless breadboard male-to-male jumpers male-to-female jumpers 22 gauge insulated hookup wire, solid Graph paper, for planning and sketching wiring diagrams and layouts.Finally, interface the display to your favorite Arduino project and write a sketch that adds colorful text and graphics to it.Īn assortment of cheap TFT LCDs ($20 ought to get you three or four)īefore you buy, check for Arduino compatibility!.With the display functional, you can then hack together a breakout board or plug-in shield.With luck, you will see text and/or graphics. Load an example sketch into the Arduino IDE, and then upload it to the attached Arduino board with wired-up TFT display.Figure out how to hook up the hardware, i.e., which display pins are wired to which pins of the Arduino.On a Linux machine, as root, copy the library archive file to the /usr/share/arduino/libraries directory and untar or unzip it. Download and install the driver library.Henning Karlsen's UTFT library works with many displays. Find out whether there is an Arduino driver available.Determine the display's resolution and the driver chip. Otherwise, it may involve matching its appearance with a picture on Google images. With luck, it will have identifying information printed on it. But, how is it possible to determine which ones will work with an Arduino? And what then? Here is the procedure: There are quite a number of small cheap TFT displays available on eBay and elsewhere. This makes it feasible to reuse them to give our electronic projects colorful graphic displays. These have been manufactured in the tens of millions for cell phones and other gadgets and devices, and that is the reason they are so cheap now. Moreover, it can display not just text, but elaborate graphics. For as low as $4 (shipping included!), it's possible to buy a small, sharp TFT screen that can be interfaced with an Arduino. No!
