In this project you’re going to build a time attendance system with MFRC522 RFID Reader and Arduino. When you swipe an RFID tag next to the RFID reader, it saves the user UID and time in an SD card put into a SD Module for Arduino. It also shows if you are late or in time accordingly to a preset hour and minute.

In this second “episode” (here the first one), we will go deeply inside Fishino features, showing the main libraries and code sketches. In the last post we have presented the Fishino UNO board, compatible with Arduino UNO but offering WiFi connectivity, a microSD slot and a built-in RTC. In this second post we begin describing…
https://youtu.be/W-IVzD2Tul0 Ever since the dawn of time, people have begun to dispense time. First was the sundial, later appeared water clock after them was the hourglass. Millennia later was created the first pendulum clock and few centuries later the electronic watch. Today I’ll show you how to make Pixie, a wristwatch that combines both analog…
Using a relay with the ESP32 is a great way to control AC household appliances remotely. This tutorial explains how to control a relay module with the ESP32. We’ll take a look at how a relay module works, how to connect the relay to the ESP32 and build a web server to control a…
In this project we will use Arduino UNO to make an awesome and cheap oscilloscope! It’s very easy to create and it required the Arduino board, some passive components and a computer with Processing IDE installed More info Build it yourself Boards, sensors and kits for projects like this one.
