Real-Time SD Card Failure Detection System

In this project, you’ll learn how to create a system that must be able to detect a malfunction in an SD card and to inform on an LCD.

On some systems, such as 3D printers, memory cards are used to save print files. Therefore, it is very important to check the memory card connection at the beginning and during the printing process.

Therefore, in case of any connection or card failure, the system must be able to detect a malfunction and inform the user on the system LCD screen.

In addition to the 3D printer, this method can be used for any system or device that uses a memory card.

Therefore, we present a circuit to test the solution, as shown in Figure 1.

Next, we will create and explain an algorithm to detect the failure or lack of connection of the memory card during the process of executing the system.”
