int main(void) {

// Setup DDR and PORT bits for the 2 input buttons // as necessary DDRC &= ~((1

// Initialize the LCD PORTB |= ((1

// Use a state machine approach to organize your code // - Declare and initialize a variable to // track what state you are in while (1) { // Loop forever // Write if/else statement here

lcd_writedata(0); // Use an outer if statement to select what state you are in // Then inside each 'if' or 'else' block, perform the desired // output operations and then sample the inputs to update // the state for the next iteration if() // Delay before we go to the next iteration of the loop }

return 0; /* never reached */ }
