The presented system is a very interesting example of the use of the popular, small AVR processor, among others in the role ... of the impulse converter. And in general, power LEDs are becoming more and more popular, cheaper and more effective. Such a diode should be powered from a current source. If we have a power supply, there is no problem. All you need is a simple current source circuit on transistors and you do not have to worry about power losses. But what to do when we want to power such LEDs with batteries?
