I want to build a 90% efficient microcontroller based LED driver circuit with current range from 25mAmps to 35mAmps with the source voltage of 7.4 volts. How can I make it using my Arduino board.
1.) 24 to 32 LED's.
2.) LED load is of 3 to 3.2 volt.
3.) 7.4 is the source voltage which is charging a 3.7 volt lithium ion battery i.e LED's wil be powered by the lithium
ion battery.
Please help.
