On the hardware side here, we use an Arduino Uno, MFRC522 RFID Sensor and an LCD Display. ... Install the respective Python libraries used in the program before use. A MySQL database as ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Initialization: The Arduino initializes the pins for the flame sensor, built-in LED, and external LED, and begins serial communication. Flame Detection: The flame sensor reads the presence of a flame ...

Getting started with the Maker Uno RP2040 board using the Arduino IDE. As mentioned in the introduction, the Maker Uno RP2040 can be powered with either a USB Type-C cable (5V) or a single-cell ...

IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

Using the RFID starter kit from Elektor provides a good basis to carry out numerous electronic experiments with the Arduino Uno. We show just how simple it can be to realize an application.

Here we build an RFID based Contactless Temperature Monitoring System using MLX90614 temperature sensor with Arduino. When employees scan the RFID card, it will measure the body temperature of ...

Using the RFID starter kit from Elektor provides a good basis to carry out numerous electronic experiments with the Arduino Uno. We show just how simple it can be to realize an application. Original ...

We build the RFID Reader and Arduino-Uno Interfacing Based automatic liquid dispenser to restrict the ... (see Fig. 2) to the Arduino program. Before uploading, connect it to the EM-18 RFID module ...
