Using a DS3231 Module with Arduino

Using a DS3231 Module with Arduino

Every computer is equipped with an internal real time clock that allows it to know the date. Arduino type microcontrollers do not have PSTN. The DS3231 module gives the Arduino the ability to calculate the date, allowing it to control time more precisely. Hardware...
Using a PIR sensor with Arduino

Using a PIR sensor with Arduino

It is possible to activate a system, such as an alarm, by detecting the presence of a person using a PIR motion sensor. In home automation, it is common practice to operate devices when a person enters a room. This is made possible by motion sensors such as the...
