A comprehensive IoT data collection and visualization system built with Laravel 12, designed to receive and display real-time data from Arduino Nano 33 IoT and ESP32 devices via TCP connections.

Abstract: This study experimentally examined the energy usage of the ESP32 and Arduino Nano microcontroller boards in active and deep sleep (power-down) modes. Both boards were powered by a continuous ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm Cortex-M4F microcontroller, but offered in a much more compact form factor. It’s ...

SparkFun has just launched the “IoT RedBoard – RP2350” and “IoT RedBoard – ESP32” boards with Arduino UNO R4 form factor based on respectively Raspberry Pi RP2350B + RM2 wireless module and ...

Recently there was a panicked scrambling after the announcement by [Tarlogic] of a ‘backdoor’ found in Espressif’s popular ESP32 MCUs. Specifically a backdoor on the Bluetooth side that would give a ...

Update 3/9/25: After receiving concerns about the use of the term 'backdoor' to refer to these undocumented commands, we have updated our title and story. Our original story can be found here. The ...

Run in the Arduino IDE the HelloWorld example with an ili9488 in SPI. In fact, you don't need an ili display to try this, because it fails at compile time. The possible wiring errors, are irrelevant ...

The Waveshare ESP32-P4-Nano is a tiny, inexpensive, low-power development board powered by a dual-core RISC-V processor. Available now from Waveshare or AliExpress for around $19 and up, the little ...

Learning electronics? Then, chances are you already know what an Arduino is, or at the very least, you've heard of it. After all, it's among the most popular electronics platforms available in the ...

Arduino is a good platform if you want to start working with electronics. The platform, specifically the Arduino Nano family, is a set of small form-factor boards that act as microcontrollers, meaning ...
