This code example demonstrates how to preform low power voltage and current measurement using the AVR EA Microcontroller

Putting your STM32 to sleep with Rust

A wireless, battery-powered recording light or "do not disturb" light. The light is controlled with two buttons on a webpage. To save power, the MCU enters deep-sleep after 11 hours, for 13 hours.

Secure unlocking over Wifi with a remote control

Fixes deep sleep on p8lite custom roms

control garden watering from anywhere, using a phone or tablet. Solar powered. ESP32

Ultra-Low Power Single push button ON/OFF controller based on ATTiny13/13A/25/45/85 for other microController and circuits application

Aparat pishti kada detektuje pokret preko PIRa. Inace (ATtiny85) spava.

This code example demonstrates usage of AVR128DB48 microcontroller for configuring external crystal as peripheral clock source in sleep. In this example, external crystal as peripheral clock source in sleep is exemplified using Real-Time Counter(RTC).

Plant Irrigation System

Low power consumption Arduino external EEPROM data logger. More than one year operation at ten minutes interval with thermistor/SHT-31, LCD and three AA batteries.

Low power voltage and current measurement using the AVR EA and MCC

ESP32Cam Time lapse camera deep sleep w. SD card and Day/Night operation

Transparent HUD for an Airsoft gun that shows how many BBs are left in your magazine and keeps track of your number of kills and deaths during a match. A XIAO ESP32-C3 is used together with a SSD1309 transparent OLED display. An IR Transmitter LED and IR Receiver sensor is used to detect BBs. Video: https://youtu.be/BZJjDX5xyRM

Testing ESP8266 capabilities: WiFi, web server, LoRa, get current time (SNTP), connection to a display (ST7735, ST7789)...

This project is a result of graduation qualification work "Development of a system for monitoring environmental indicators affecting plant life, with automatic irrigation function"
