RTC Battery for Raspberry Pi 5
RTC Battery for Raspberry Pi 5
The RTC (Real-Time Clock) Battery for Raspberry Pi 5 is a small, compact component designed to provide a reliable timing source for the Raspberry Pi 5 single-board computer. This component is essential for applications that require accurate timekeeping, even when the Raspberry Pi is powered off or in sleep mode.
The RTC Battery module is responsible for maintaining the current date and time on the Raspberry Pi 5, ensuring that the system clock remains accurate and up-to-date. This is achieved through a dedicated Real-Time Clock (RTC) chip, which is powered by a small battery. The battery provides a continuous power source to the RTC chip, allowing it to maintain the clock even when the Raspberry Pi is turned off or disconnected from a power source.

```python
import rtc# Initialize the RTC
rtc.init()# Set the system clock to 2023-03-15 14:30:00
rtc.set_datetime(2023, 3, 15, 14, 30, 0)# Retrieve the current system clock
dt = rtc.get_datetime()
print("Current datetime:", dt)
```
### Example 2: Scheduling with RTC and PythonThis example shows how to use the RTC Battery for Raspberry Pi 5 to schedule a task to run at a specific time using Python's `schedule` library.
```python
import rtc
import schedule
import time# Initialize the RTC
rtc.init()# Set the system clock to 2023-03-15 14:30:00
rtc.set_datetime(2023, 3, 15, 14, 30, 0)# Define a function to run at 15:00 every day
def daily_task():
print("Daily task executed!")# Schedule the task to run at 15:00 every day
schedule.every().day.at("15:00").do(daily_task)while True:
schedule.run_pending()
time.sleep(1)
```
