LED light controller design, ATMEGA8 series

If you want to change the LED pin, please modify the hardware.h file. If you want to modify the brightness of the LED, modify the TImings section definition in globals.h. This design has two external buttons, one is to select the working mode, and the other is the power switch. When you press the mode button for more than 1.5 seconds, enter the automatic mode and all the preset modes will be automatically demonstrated.

Eight LEDs are connected directly to Vcc and do not require a current limiting resistor. This production uses a synchronization timer and uses sleep to save power.
