List of my latest Arduino Tutorials:
- Controlling your Arduino Projects through Serial Communication
Introduction Serial communication is the process of sending messages between a sender and a receiver one bit at a time. Most of the commercially available microcontroller supports this protocol out of the box. In this post, I am going to share with you how you could take advantage of this protocol to control your Arduino projects by using the messages through the serial communication interface. We are going to control our electronic components attached to an Arduino Uno board with messages coming from our laptop (or desktop) computer. If you want to see a demo of this project in actual… Read more: Controlling your Arduino Projects through Serial Communication - Using ESP32 SoftwareSerial in your Arduino ProjectsIntroduction If you have worked with the Arduino Uno R3 board, I am sure that you have used SoftwareSerial library in your projects. The board itself only contains a single hardware Universal asynchronous receiver-transmitter (UART) port in Digital Pins 0 (RX) and 1 (TX). If you have multiple sensors that use Serial communication then you need to convert some of the digital pins as UART using software using the SoftwareSerial library. In this post, I will show you how you can configure your ESP32 or ESP8266 microcontroller to use SoftwareSerial in your Arduino programs. If you want to see a… Read more: Using ESP32 SoftwareSerial in your Arduino Projects

- ESP32 – Read DHT22 Sensor using ArduinoThis post will show you how you to interface your ESP32 with your DHT22 sensor running the Arduino framework.
- Using Arduino with BME280 plus a weather station projectThis post will show you how to interface your Arduino code with the BME280/BMP280 sensor with a weather station project using ESP8266/ESP32
- Arduino officially supports MicroPythonThis post explores how to get started with the Arduino support for MicroPython using the Arduino Lab for Micropython
- Arduino RFID Database Security System: Program Arduino and ESP8266In this article we are going to program our Arduino RFID Database Security System. We will configure the Arduino to read the MFRC522 RFID Reader and retrieve the RFID code. The RFID code is then sent thru the ESP8266 ESP-01 through serial communication.
- Arduino RFID Database Security System: Designing the ProjectThis article describes how to design an Arduino RFID Security System that uses the ESP8266 ESP-01 to communicate with the database
