This weeks PAW is something that I have wanted to have for a long time but never gotten around making – until now that is 🙂 Everytime I solder a SMD LED on a pcb I have to turn on one of my multimeters and flip it over to diode-test mode and then probe the […]

Have you ever heard of TFT LCD screens? They are great ways to display information from your Arduino, or display pictures. The Arduino team just released an official TFT LCD screen with their new Robot at Maker Faire 2013. It’s very easy to get started with!! This tutorial will show you how to get the

LCD displays are commonly supplied as a module with a built-in driver circuitry usually mounted on a PCB at the rear of the module. While this strengthen the module mechanically, it has some drawbacks such as it increases the thickness of the display module and raises the manufacturing cost. NXP semiconductors describes the Chip-On-Glass technology

Displays from 4D Systems can be used even if you don´t have experience with programming of graphic displays. Let´s look at how … No doubt, that a graphic display significantly improves a user interface of practically every product. Maybe a little less obvious is the fact, that already a relatively small display with a touch
