The goal of this tutorial is to teach beginners the basics for a perfect welding of an electronic circuit. Being a very practical argument we preferred a visual approach built on a fair use of images, rather than an overly discursive dissertation. The practicality of this guide is also reflected in the use of the LCD display 1602A, the component that we chose for this tutorial and that's also very common in a variety of Arduino based projects. It is also robust enough to fit a beginner's needs.
