If you want to learn how to communicate with an internet time server to get the current time and date, please read How to Keep Track of the Date and Time on an Arduino. The clock source of a time server can be another time server, an atomic clock, or a radio clock.Īn RTC is a very popular and accurate source of time and date in an embedded system like an Arduino because it has low power consumption. Time Server– A Time Server is a computer on a network that reads the time from some reference clock and distributes it to the network.Global Positioning Device (GPS) – A GPS device communicates with satellites to determine its location anywhere in the world.It uses a back-up battery to maintain the time in the event that the main power source is removed. Real-Time Clock (RTC) – A Real-Time Clock, or RTC for short, is an integrated circuit that keeps track of time.We can get it from a Real-Time Clock (RTC), a GPS device, or a time server.
There are several ways to get the current date and time. How to Get the Current Date and Time on an Arduino Depending on the project, having a way to get the current date and time is very useful. Arduino-based clocks use the current time as a timer for reminders or to execute a scheduled command via the Arduino’s I/O pins. Another example is for an Arduino digital clock or calendar. For example, an Arduino Weather Station needs timestamps in recording weather data. One use for it is for recording/log purposes. Keeping track of the current date/time for an Arduino has many purposes.
