PIC16F628A PROGRAMMABLE DIGITAL TIMER

Programmable transfers discover use in various robotization applications, for example, programmed road light control, watering and pump control, HVAC, home computerization, power plants mechanization in commercial ventures, and so forth. This article portrays how to fabricate an entirely possible, one-channel programmable hand-off switch utilizing the PIC16F628A microcontroller. It permits you to set both ON and OFF time. The greatest time interim that you can set for on and off operations is 99 hours and 59 minutes. Another interesting component of this anticipate it offers cyclic choice, which implies you can run it in a persistent circle of ON and OFF cycles. The gadget can be modified through 4 push switches. The programming menu and device status are shown on a 16×2 character LCD. The planning determination of this hand-off clock is 1 minute. The clock likewise spares the client inputs to its internal EEPROM with the goal that it can hold these qualities after any force supply interfere. Here are the rundown of the elements that this clock gadget has:
