A Graphic LCD module is a type of liquid crystal display that can represent images, letters, and numbers that are generated through customer or user software. These displays are made up of dot matrixes. Dot matrix displays are identified by two sets of numbers. An example of this is a 128 x 64. This screen contains 128 points along the X, or horizontal axis, and 64 points along the Y or Vertical axis. Each of these points, sometimes referred to as a pixel, can be turned on and off independently of one another. The user uses software to indicate at each point when to turn on and off.

In this section we will find GSM modules for mobile communication that we can use in our Arduino, Raspberry or other projects.
The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe protocols for second generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets. It was first deployed in Finland in December 1991. In the mid-2010s, it became a global standard for mobile communications, achieving a market share of more than 90% and operating in more than 193 countries and territories. .
2G networks were developed as a replacement for first generation (1G) analog cellular networks. The GSM standard originally described a circuit-switched digital network optimized for full duplex voice telephony. This expanded over time to include data communications, first by circuit switched transport, then by transport of data packets over General Packet Radio Service (GPRS) and Enhanced Data Rates for GSM Evolution (EDGE).
Subsequently, the 3GPP developed the third generation (3G) UMTS standards, followed by the fourth generation (4G) LTE Advanced standards and the fifth generation 5G standards, which are not part of the ETSI GSM standard.
