FAQ:
Q: Why is there a clock in my Arduino?
A: 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. Depending on the project, having a way to get the current date and time is very useful. There are several ways to get the current date and time.
Q: What is an Arduino Uno clock?
A: Arduino UNO is one of the most famous board in Arduino family after Arduino Duemilanove. It is the latest design of the basic USB board. It comes with 6 analog inputs, 14 digitals output where 6 of themsupport PWM, and 16Mhz clock speed. Arduino UNO comes with 6 analog inputs and 14 digital I/O where 6 of them are PWM outputs.
Q: What is a matrix clock?
A: Matrix clock. A matrix clock is a mechanism for capturing chronological and causal relationships in a distributed system. Matrix clocks are a generalization of the notion of vector clocks. A matrix clock maintains a vector of the vector clocks for each communicating host.
