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. Proteus Simulation FileĪlso in this project there is a Proteus simulation file inside of “sim” folder. The microcontroller doesn’t generate audio frequency, just it pulls up and down T1 and causes the Buzzer’s beep. 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:įurthermore you can compile the project with ctrl+F9. Alarm Clock Project Compilationīefore compiling the project, go to “headers.h” file and Search for “#define SIM”. The 16×2 character LCD pins already has been set in the program (According to the schematic). Also the BOD is enable to check the voltage if it is not under 2.9v. The microcontroller uses an external crystal 8.000000MHz oscillator. The source code of project in our store: Alarm Clock, Calendar and Temperature Meter With AVR ATmega8A The tested compiler revision is CodeVisionAVR 3.12 It shows hour, minute, second, temperature, year, month, day and the day of week.
The calendar can be toggled between Gregorian calendar and Persian calendar. To re-compile or check out the source code, open “ClockCalendar.prj” with codeVision AVR software. There’s a source code folder in this project which contains the CodeVision program files (C) and pre-compiled HEX file. The “Alarm Clock And Calendar” project uses this microcontroller as its main processor and a standard 16×2 Character LCD without using any additional module. ATmega8A is an AVR 8 bit microcontroller which has 28 pins.
