Electronic, 3D printing and embedded programming
Wi-Fi is a wireless networking technology that allows devices such as computers, smartphones, and other electronic devices to connect to the Internet and communicate with each other without the need for physical cables. It uses radio waves to transmit data across a network, enabling users to access the internet from anywhere within the range of a Wi-Fi hotspot. Wi-Fi is based on the IEEE 802.11 family of standards and supports various frequencies, including 2.4 GHz and 5 GHz, to provide high-speed internet connections. It has become ubiquitous in modern life, found in homes, offices, cafes, and public spaces worldwide, offering convenience, mobility, and flexibility in internet access. Wi-Fi networks can be protected with encryption methods like WPA2 to ensure secure data transmission, making it safe for transmitting sensitive information.
Remote debugging is an essential feature for any embedded system, including Arduino-based projects. The ESP8266 WiFi module has gained popularity for such applications, especially when used with ESP-LINK firmware. This article aims to guide you through setting up an enhanced remote debugging environment using Arduino, ESP8266 (NodeMCU and ESP01), and ESP-LINK firmware.
Boost your K40 CO2 Laser’s functionality with an ESP32-CAM housed in a 3D printed case. This setup allows for real-time monitoring of your laser engraving and cutting processes, enhancing both safety and precision. Ideal for users seeking to optimize their workflow and maintain control over their projects.
This article will guide you through the methodology of remotely programming an Arduino UNO using ESP8266 modules, specifically focusing on NodeMCU and ESP01, utilizing the ESP-Link firmware. This firmware acts as a bridge, enabling WiFi and serial communication, thereby changing the way we interact with microcontroller boards like the Arduino UNO through ESP8266.
Unlock the potential of wireless Arduino UNO programming with DT-06 and ESP-Link Firmware. Our guide explores the seamless integration of WiFi and serial communication, transcending the DT-06’s original firmware limitations, and upgrading remote device management in the IoT domain
We have already addressed the topic of remote wireless programming via Bluetooth of an Arduino UNO in our previous article titled “Arduino Remote/wireless Programming” however, thanks to the feedback and questions from our readers, we have decided to delve even deeper into this subject, exploring the possibilities that WiFi connectivity offers.
DOIT DT-06: high-resolution pinout and specs
One of the most important features of the ESP32 is the ability to perform over-the-air (OTA) updates, which allows developers to remotely update the firmware of the device without the need for physical access.
In this article, we will explore how to perform an OTA update on an ESP32 using the Arduino IDE. We will cover the entire process, including updating the filesystem and firmware, as well as securing the OTA update with a password.
Even though Raspberry Pi Foundation has released the Pico W version, I still find this tutorial useful for adding WiFi to rp2040 boards using an ESP32.
We will use an esp32-wroom-32 (or esp32-s) as WiFi coprocessor and the full potential WiFiNINA library to handle it.
For me, It’s very important the network connection and network limitation on STM32F4 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.
For me, It’s very important the network connection and network limitation on STM32F1 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.
