Last time, I talked about how my storage situation and my cheap nature led me to build an RC joystick controller with a cell phone app and an ESP8266. The key to making this easy was to use the GUI ...

An Arduino sketch to connect an INA-219 module to an ESP dev board and measure Voltage, Current, Power, Energy Consumption and Costs via the Blynk mobile app. An arduino sketch to connect the ...

To show gas sensor data in Blynk through IoT, you’ll need to use a gas sensor (e.g., MQ-2, MQ-135), a microcontroller with IoT capabilities (e.g., ESP8266, ESP32), and the Blynk app. VCC to 3.3V or 5V ...

For many people who like to build things that use Arduino to operate one of the most difficult parts is making an app or software to control the project. A new program called Blynk has turned up ...

FlashESP is a web-based tool allowing the development of Arduino sketches and firmware flashing for ESP32 and ESP8266 hardware platforms. I initially thought it was similar to ESP Web Tools for ...
