Iam new to programming , so since am doing avr based project first time i need help from you . i want to interface a lcd, led ,speaker and few switches . the purpose of lcd is to display the date and time with status changes from hour to hour updating status .and the led to indicate the time hour is about to complete and the speaker act as an scheduled alaram daily 7 times . and finally switches to change or update date and time .
Please help me out with circuit daiagram using atmeg16 and code for it . and also suggest me as source to learn programming so that in future i can do it by myself .
thankyou!Hye sanju kumar,
Before explain anything, i think you know basic concept of C programming. First learn the I/O device interfacing with AVR like led interfacing, keypad interfacing, LCD interfacing etc., After you can go on your application.
Use the modular approch to develop your application.
– Devide your application in subtask like how to interface lcd
– Write code for Interfacing device
– Run and test the code on hardware(i.e. development board or breadboard circuit )
– Solve each bugs
– Now make flowchart and algorithm for your application
– Prepared Circuit diagram
– Write code for your application
– Run and test on your application hardware
– Find the bungs and solve it.
Note : In EngineesGarage , Lots of C programming tutorials and also various small interfacing tutorials available for various controller. You can learn from it. It will be helpful for you.
