Analog Freezer Alarm
A time-delayed alarm is a useful device that can be used in various scenarios, such as security systems or to remind you to close the freezer properly. The alarm is triggered after a certain amount of time has elapsed, providing a delayed response. In this article, we will discuss the design of a time-delayed alarm using two NE555 timer ICs and some passive components. The NE555 timer IC is a popular integrated circuit that can be used in various applications, including timing and oscillation, both will be used in this design.
