This is the FIRST PROGRAM in your course of FUNDAMENTALS OF ROBOTICS. To use this program, you must use our robotics kit already supplied to you.
If you do not have this kit, then you can purchase our distance learning programme in robotics or contact us to join our regular batches of robotics.
Now read the following program carefully and work as per the given instructions, to enjoy your first program in robotics.
To use this program directly for your robotic kit, copy it, create new project in AVR Studio and then paste it into the coding area. Then compile it.
/*
Level II project of 4 LEDs Blinker
Applicable to ATMega8/16/32/128
Designed by: Vidyasagar Academy, Akola

*** CONNECTION DETAILS OF KIT ***
PB4-PB1 : output pins of PORTB, connected to 4 LEDs

{ // while loop brace opened
PORTB=0b00000000; // PB4-PB1 producing '0' output
// so the 4 LEDs are OFF
_delay_ms(1000); // the LEDs remain OFF for 1000ms=1sec
PORTB=0b00011110; // PB4-PB1 producing '1' output
// so the 4 LEDs become ON
_delay_ms(2000); // the LEDs remain ON for 1000ms=1sec
} // while loop brace closed
} // main function brace closed

=== HOW TO USE AND RUN THIS PROGRAM IN YOUR KIT? ===
1) First read the program carefully. Understand the steps as taught to you.
2) Connect your kit to USB port.
3) Burn the 'hex' file into your kit.
4) All the LEDs connected to PB4-PB1 will glow for some time
5) After some time all the LEDs will be OFF.
6) This on/off will repeat continuously till the battery is connected.
9) Is it working? Nice! You did it.
10) Now don't forget to give your feedback.
