The  DS1307 Integrated Circuit  from Chawla Electronic is Serial Real-Time Clock is a low-power, full binary-coded decimal clock plus 56 bytes of NV SRAM. The DS1307 Serial Real-Time Clock is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially via a 2-wire, bi-directional 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 operates in either the 24-hour or 12-hour format with AM/PM indicator. The DS1307 has a built-in power sense circuit that detects power failures and automatically switches to the battery supply.  Features:-
 Real-time clock (RTC) counts seconds, minutes, hours, date of the month, month, day of the week, and year with leap-year compensation valid up to 2100 
56-byte, battery-backed, n...

1N4007S Diode A diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture below. For  1N4007S Diode , the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible. The power dissipation of this diode is 3W.   1N4007S Diode Datasheet These Axial Lead Mounted Rectifiers are used for General-Purpose Low-Power Applications ABSOLUTE MAXIMUM RATINGS (Ta = 25ºC)   DESCRIPTION   SYMBOL 1N 4007S   UNIT   Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blockng Voltage V RRM V RWM V R   1000   V   Non-Repetitive Peak Reverse Voltage ...
