Really tiny library to basic RTC functionality on Arduino. DS1307, DS3231 and DS3232 RTCs are supported.

Arduino tiny and cross-device compatible timer library

I2C EEPROM library. Split from uRTCLib. This library controls any I2C EEPROM, independent ones or incorporated on DS1307 or DS3231 RTCs.

Broker to manage multiple interrupts with uTimerLib

Arduino, ESP8266 and STM32 7-segment multiplexed displays library - uSevenSegmentLib

IR-MQTT-ESP, IR multiple repeater using MQTT for ESP8266 and ESP32 microcontrollers

I2C RAM/FRAM/MRAM library, derived from uEEPROMLib. This library controls any I2C RAM/FRAM/MRAM. Based on FM24CL16 FRAM.

This Arduino sketch implements properly a simple pin change interrupt on any ESP microcontroller (ESP8266 and ESP32).
