![]() By pressing SET, the minute will blink and can be set with UP and DOWN.īy pressing again the hour will blink, then year, month and day. There are 3 push buttons, SET, UP and DOWN. COFF file by double click on the microcontroller, then run the simulation. Open it with Proteus Schematic and set the project. The microcontroller doesn’t generate audio frequency, just it pulls up and down T1 and causes the Buzzer’s beep.Īlso in this project there is a Proteus simulation file inside of “sim” folder. RT is a 10K Ohm NTC resistor and R4 is a 20K ohm pull up resistor. ![]() There is a temperature sensor which connects to the PC4. ![]() There are 3 push buttons to set the clock, alarms and calendar. In the power sector, there’s an input for 3-4 volt battery, for when the circuit is unplugged from the main 5v power source, to saving the time data. Here’s the schematic plan which is compatible with the project. In case you are going to test the program with “Proteus Software”, it should not be logged.īut if you’re going to upload the program into the microcontroller, log it with two slashes: The 16x2 character LCD pins already has been set in the program (According to the schematic).īefore compiling the project, go to “headers.h” file and Search for “#define SIM”. Also the BOD is enabled to check the voltage if it is not under 2.9v. The microcontroller uses an external crystal 8.000000MHz oscillator.
