This is a fully functional retro gaming console built around an ESP32, a 128×64 I²C OLED screen, and a KY‑023 analog joystick. It runs three games, stores high scores permanently, plays sound effects ...

In this video, I’m building a LoRaWAN Class A sensor node using an ESP8266, BME680 environmental sensor, and REYAX RYLR993 LoRa module. The device measures temperature, humidity, pressure, and gas ...

It wasn’t that long ago that projects with cellular connectivity were everywhere, but with 2G no longer universally available, glory days of cheap 2G modules seem to be on their way out. So when [Data ...

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 ...

A simple and robust Arduino library for using the deep sleep features of the ESP32-C3, abstracting away the complexities of the ESP-IDF. A dedicated Arduino library wrapping ESP-IDF’s deep sleep and ...

Seeed Studio XIAO 7.5″ ePaper Panel interfaces an XIAO ESP32-C3 USB-C board and mainly targets the Smart Home market with support for ESPHome, but the monochrome ePaper display is also programmable ...

I have made considerable progress on this project. I withdraw my initial assessment that this is a dead end. Read on. A friend is very involved with the support of local walking trails. His group ...

The Arduino platform has been popular among hobbyists and professionals for many years. However, as technology advances, so do the options available for those looking for an alternative to the Arduino ...
