In our ESP32 projects and tutorials, we recommend using the Arduino IDE to program the ESP32 development board. However, in some Windows computers it’s a bit tricky to install the …
In this project you’ll create a standalone web server with an ESP32 that controls outputs (two LEDs) using the Arduino IDE programming environment. The web server is mobile responsive and can be accessed with any device that as a browser on the local network.
An oscilloscope is a great tool for debugging and better understand what is going on with your circuits. Unlike a multimeter that only shows the voltage at a specific moment, …
This post is about the WS2812B LED strip, which is an addressable RGB LED strip. The information in this post also works with other similar LED strips, such as strips of the WS28XX …
In this post I’m going to review the TEVO Michelangelo 3D printer. The TEVO Michelangelo is a small desktop 3D printer that comes fully assembled. All you have to do …
In this tutorial we’ll explore the basic principles of LoRa, and how it can be used with the ESP32 for IoT projects using the Arduino IDE. To get you started, …
This project shows how to log data with timestamps to a microSD card using the ESP32. As an example, we’ll log temperature readings from the DS18B20 sensor every 10 minutes. …
This project shows how to use MQTT communication protocol with the ESP32 to publish messages and subscribe to topics. As an example, we’ll publish BME280 sensor readings to the Node-RED …
In this project you’ll use an infrared (IR) receiver and an Arduino to control 3 LEDs with a remote control. This is useful to re-use old remote controls or give some functionally …
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 …
In this project we’re going to show you how to request sensor data via SMS with the Arduino. As an example we’re going to request the temperature and humidity from …
In this post we’re going to to take a look and review the JYETech DSO150 digital oscilloscope. An oscilloscope is an essential tool in electronics but its price may be …
