Putting your STM32 to sleep with Rust

Fixes deep sleep on p8lite custom roms

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

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.

Plant Irrigation System

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).

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

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

Small portable ESP32-based motion detector - Informs you if your pet or a burglar is at the back door and wants in.

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
