I'm just going to wire my new setup based on Mega 2560 (Crius AIO Pro+ext. board), and I want to use the BUZZER and LED TOGGLE functions for battery monitoring!!!
Please give me an advice how to connect the 12V LED stripes to the output of the Mega. For Buzzer, should I connect the proper type of buzzer directly to the output? Should I use a buzzer soldered out from a LIPO watcher?
I'm looking for a safe solution, so LEDs connected directly to the MEGA's output is not an option. I'd use small circuit based on a FET. Small hand drawed circuits are wellcome....

PS.: I checked, for a MEGA 2560 BUZZER should connected to Nr.32 output and for LED TOGGLE Leds sould connected to the Nr. 13 or 30 output. Am I right???
