Sketch that explain arduino use sleep mode with a rtc
goals
- time setting from the “Wire.h” library
- detail how to set up the standby of a UNO
- Measurement via [USB voltmeter ammeter module] (https://fr.aliexpress.com/item/1005001847555926.html) therefore not very precise
| Unit | active | sleep |
|---|---|---|
| Volt | 5.1 | 5.1 |
| Amp. | 0.02 | ~0.0 |
It tells me 65mAh
use
- Arduino UNO or other board equivalent
- RTC DS3231
