The Smart SMS Alert System using Seeed Studio Xiao ESP32 is one of the compact IoT projects that uses an HC-SR04 ultrasonic sensor to detect nearby movement. The system acts like a motion detector ...

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 ...

Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been working since the release of the ESP-IDF 5.1 ...

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 ...

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, ...
