I have an easy project but if you have enough experience about it.
-I have a led which typical forward voltage 2VDC and current value is 20mAh.
-I need to drive this led at the different brightness levels. And the levels will be changed by pushing a tact switch. And I have to lock tact switch by pushing 3 seconds and unlock by pushing 3 seconds and pushing 5 seconds to turnoff/turnon the led. So apparently i will need a microcontroller.
-The most important part is that the lowest power consumption is the key point of this product. For example, the lowest power consumption of a similar product is 4uA yes 4 microampere.
-The system supplied by CR2032(3V).
-Could you suggest a appropriate soluiton for this challenging project? Which microcontroller should i use? Maybe additionaly i should use a led driver i don't know. I don't want to restrict your idea.
