Connect an ESP8266 module to an Arduino Nano and control it with Blynk

We are going to build a circuit that is connected to an app build with Blynk. For this we connect an Arduino to an ESP8266 module and connect it through Wifi. This example uses an Arduino Nano, of course you may use an other type of Arduino, eg. the Uno. This guide assumes you already have … Continue reading Connect an ESP8266 module to an Arduino Nano and control it with Blynk

Add RFID identification to a Java application

If you have an RFID reader module attached to your computer (via a USB serial connection) you can read RFID data from a Java application. For instance, you can use the unique id (Card UID) to identify something or someone. You can learn how to build you own RFID reader here. To use serial communication in … Continue reading Add RFID identification to a Java application

Build an RFID reader with Arduino and the RC522 RFID module

The RC522 RFID module is a cheap module which comes with a card and a dongle. You can buy it at our local electronics shop the STORES for € 4,85 (search for ‘rfid’ in the pricelist). Only thing you have to do before you can use it is solder the header. If you are unfamiliar with … Continue reading Build an RFID reader with Arduino and the RC522 RFID module
