D printed breadboard designs optimized to leave as many rows as possible for the Raspberry Pi Pico and ESP32 development ...

ESP32 text to speech becomes a really helpful feature that can turn an embedded project from good to really useful. Whether you're building a handheld device, automation panel, safety monitor, or ...

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 ...

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 ...

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 ...

When you think of Arduino, your mind immediately pictures an Arduino Uno with its teal color, bulky USB port, and long microcontroller chip sitting on a socket, and you're not alone. The Uno is such a ...

If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...

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).
