RTC I2C DS1307 AT24C32 Real Time Clock Module in Pakistan
What is an RTC?
A real time clock is basically just like a watch – it runs on a battery and keeps time for you even when there is a power outage! Using an RTC, you can keep track of long timelines, even if you reprogram your microcontroller or disconnect it from USB or a power plug.
Most microcontrollers, including the Arduino, have a built-in timekeeper called millis() and there are also timers built into the chip that can keep track of longer time periods like minutes or days. So why would you want to have a separate RTC chip? Well, the biggest reason is that millis() only keeps track of time since the Arduino was last powered – . That means that when the power is turned on, the millisecond timer is set back to 0. The Arduino doesn’t know that it’s ‘Tuesday’ or ‘March 8th’, all it can tell is ‘It’s been 14,000 milliseconds since I was last turned on’.

1 Channel Relay Module For Arduino In Pakistan
Key Features of 1 Channel Relay Module For Arduino In Pakistan:
Isolation: The relay provides electrical isolation between the low-voltage control side (Arduino) and the high-voltage load side, ensuring safety during operation.
Easy Integration: The module is designed to be compatible with most Arduino boards. It often comes with clearly labeled pins and can be connected easily using jumper wires.
Indicator LED: Many relay modules feature an LED that indicates whether the relay is activated, making it easier to debug and monitor.
Operating Voltage: Most 1 Channel Relay Modules operate on 5V DC, making them perfect for direct use with Arduino without the need for additional voltage regulation.
