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 ...

Abstract: The accelerated development of the Internet of Things (IoT) in Fifth-Generation (5G) networks has highlighted the importance of exploring energy efficiency during run-time. It is imperative ...

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 ...

Nobody doubts the utility of the Arduino Nano and its many clones, and chances are good you’ve got at least one or two of the tiny dev boards within arm’s reach right now. But as small as it is, the ...

For years, there has been a clear distinction between the Arduino and Raspberry Pi boards. There are some things the Arduino can do that the Raspberry Pi can't, and vice versa. When you think of ...

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 ...

Here are the compilation results using ESP32 S3 Dev Module and Arduino nano ESP32 as board. I used the example code Adafruit MCP23017 Arduino Library (mcp23xxx)blink).

The piano has been around for a long time now. Not long after its invention, humans started contemplating how they could avoid playing it by getting a machine to do the job instead. [vicenzobit] is ...
