Overview Nowadays, learning about IoT devices operation and implementation is so essential due to the increasing use of IoT systems. In this tutorial, we are going to make a fingerprint attendance device with Arduino, which in addition to storing the logging information and working hours on the memory card, uploads this information on the Thingspeak platform as soon as it is connected to the Internet and You can download this information from the panel in various formats, such as CSV.https://electropeak...

Overview In electronic projects, performing operations at a specific time or showing the time to the user has always been one of the challenges ahead. The first common solution to this challenge is to use RTC ICs such as DS1307, Which are not usually accurate (for more information, see "How to Use DS1307 RTC Module with Arduino & Make a Remider?"). A newer and more accurate solution is to receive the time and date from a central server via the Internet. What You Will Learn ...
