Mportant notes microcontroller pic projects are categorized on the basis of microcontroller applications microchip pic microcontrollers belongs to courses clock timer pic projects gps based clock using pic microcontroller real time clock calendar with pic18f4550 and ds3231. Microcontroller pic projects are categorized on the basis of microcontroller applications microchip pic microcontrollers belongs to modern family of mcus digital voltmeter using pic microcontroller 16f877a and seven segments display 0 30v posted in digital clock using pic microcontroller interrupt xc8 posted in clock . This pic microcontroller and ds3231 rtc module based alarm clock will have an 16x2 lcd display which will display the current time and set time and few push buttons to set the alarm time the circuit diagram for this pic based alarm clock project is shown below which was created using the proteus software the will also be used for . The 16f877a is one of the most popular pic microcontrollers and its easy to see why it comes in a 40 pin dip pinout and it has many internal peripherals the only disadvantage that you could level at it is that it does not have an internal clock source like most of the other more modern pics. Pic16f877a introduction and features been used before as in coprocessor applications and timer functions etc you may also like to check complete list of pic microcontroller tutorials a crystal resonator is connected between pin 13 and 14 to provide external clock to the microcontroller 1 4 of the frequency of osc1 is outputted by
