DS1307 (Real Time Clock IC) Arduino Mega The TC output is normally

The TC output is normally LOW and goes HIGH when a circuit reaches zero in the count-downmode or reaches '15' in the count-up-mode

Very Easy to monitor water level as the output to analog signal is directly proportional to the water level

Support maximum 80 voice commands

Surface Mount Devices: through-hole mounting

The 74HC Family use silicon gate CMOS technology to achieve operating speeds similar to the LSTTL family but with the low power consumption of standard CMOS integrated circuits

DS1307 (Real Time Clock IC) Arduino Mega The TC output is normallyIntroduction: The DS1307 serial real time clock (RTC) is a low power, full binary coded decimal (BCD) clock calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus. The clock calendar provides seconds, minutes, hours, day, date, month, and year information . The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock
