More than 20 years ago, the inkjet printer became the preferred medium for rapid prototyping of electronic devices, and it has now become an integral part of the design and fabrication process. Often their applications are not limited to the printed page, as they can provide means to transfer data to or from other media, such as compact disc or magnetic tape, via the use of an interface chip. Inkjet printers are widely used in prototyping and to generate artwork for printed circuit boards and design documentation, because of their flexibility and low cost. The inkjet printer is based on a printhead that ejects droplets of a liquid-based ink when triggered by electrical signals generated by a microprocessor. These signals activate the heating elements which vaporize the ink and eject it on to the substrate. The droplets «Land» on the substrate individually or in two-, three- or four-color pattern. Inkjet printheads can be easily detachable from the printer and replaced by users, to avoid the need to replace the entire printer head in the event of a defect. The advantages of this are its relative low cost and its ability to easily be adapted to print in a variety of different media, such as paper, film, fabric and other materials, for a variety of purposes. Inkjet printers have therefore become the preferred medium for rapid prototyping of electronic devices, and are widely used in prototyping and to generate artwork to be printed on circuit boards as well as design documentation, because of their flexibility and low cost.
I have found this tutorial very useful. I´d liketo share my experience: when tried to get the I2C address using the sketch, but my Esp 32 couldn`t find it. After several hours searching the Internet for the cause of the problem, i finally found the crasy cause: The SDA/ SCL pins of the I2C were touching some points of the LCD PCB circuit. Once inserting a smallpiece of paper card for electric insulation, the LCD is working very well. Thank you for your magnificent site. d2c66b5586
