TLDR
Using the Arduino board, Ethernet Shield, and RFID module, we learn to assemble, solder, and program the device to mark the time of arrival and departure of employees. In the next article, we will make a small server script that will receive and process requests. The device must read the RFID tag and send it to the server via HTTP requests. It should be possible to switch to the mirror server in case of problems with the main server. We will store all the stored information in a 4-byte int, which is sufficient for most tasks.via the TL;DR App
