Development of data communication trainer with hands-on and remote laboratory hybrid system

Abstract

Data communication is the process of sending data that involves two or more devices connected to the network. This is influenced by several factors, depends on the type of data and data conversion media. The data conversion component can be in the form of RS232, which uses max232 IC as a conversion from TTL to Serial data or vice versa. This tool is a development of a data communication trainer where can see the characteristics of data communication via graphic LCD. Input from the trainer can be in the form of logic sent through the LCD touchscreen and received by the microcontroller. The data input will enter an Arduino, as a control component. The Arduino will process the input data and send it out as signal corresponding to the input data along with the signal characteristics. This tool is also equipped with an IoT system where input data can be put in from the internet network, and the output signal will appear on the page provided. The application of IoT to this tool makes it a hybrid system where can be accessed either directly in the lab, or via the internet.
