Dear all
I am using 16x2 LCD with ATmega32 microcontroller.
I need to save my power so I want that LCD back light should remain OFF during day time and when it is needed I should have switch to ON it.
the two intrrupts are busy in my circuit.
can I add a button (ON-OFF switch for it directly connected to 15 and 16 pin with supply.
