By utilizing a photo resistor, this LED can be used to wake up a Ardunio from deep sleep and log the time of the blink to an SD card.\n\n## What you need\n* [Ardunio Pro Mini 3.3V with Serial-Adapter](https://www.amazon.de/dp/B086ZN9M1J) (Remove the the power LED to reduce power consumption in deep sleep)\n* [Tiny RTC I2C DS1307](https://www.amazon.de/dp/B07DJ4QL1L) (Remove R2 and R3 to reduce power consumption)\n* [10K Poti](https://www.amazon.de/dp/B07X6RR6F8)\n* [Photo Resistor](https://www.amazon.de/dp/B08SC1M7V7)\n* [Li or LiPo Battery (1000mAh - 3000mAh)](https://www.amazon.de/dp/B07XF1FTGY)\n* [Micro SD-Card with SD Adapter-Card](https://www.amazon.de/dp/B00M55C0VU) (Can by directly soldered to the SPI pins of the Arduino)\n\n## Wiring\n![](sketch.png)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarc56k%2Felectricitymeterlogger","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmarc56k%2Felectricitymeterlogger","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarc56k%2Felectricitymeterlogger/lists"}
