Technical Tasks

In today's world, time plays a critical role in almost every aspect of life. The ability to track time with precision and accuracy is essential, whether you are managing a large corporation or building a small hobby project. A real-time clock (RTC) is an electronic device that is used to track time with high accuracy. The DS3231 RTC module is one of the most popular RTC modules available in the market. This article will provide an in-depth overview of the DS3231 Real-Time Clock and discuss how it can be used in an RTC project with Arduino interfacing. DS3231 Real-Time Clock: The DS3231 is a low-cost, highly accurate, and highly stable real-time clock (RTC) module. It is a popular choice among hobbyists and professionals alike due to its ease of use and low power consumption. The module is designed to provide accurate timekeeping and datekeeping in a wide range of applications, including time-based functions, alarms, and calendars. The DS3231 RTC module is a highly integrated

 FM Transmitter Circuit FM Transmitter circuit uses radio waves to communicate data across space, FM means Frequency Modulation this modulation works when ever there is a data that is to be transmitted over a Radio Frequency which could be as low as 3k Hz or as high as 300 G Hz data alters the carries signal frequency according to its high and low peaks, frequency variations in carrier signal is now actually data which is being transmitted over it. Data which is transmitted over FM transmitter could be of Analogue or Digital nature depending on what is being transmitted, for example Analogue data could be Sound from microphone, Temperature form lm 35 which is analogue temperature sensor, Light intensity variations from LDR or FM transmitter might be used for transmitting Digital Data sound stream from digital microphone, file being transmitted, internet data. Circuit Diagram Starting from the LHS first transistor 2n2222 is for microphone and second transistor is for FM oscillator and t
