ECE 3 - DIY Backlight LED Tester Prototyping

Design and prototype of my 3V and 6V LED tester to test backlight LED strip up to 18LED strip for 3V or 9LED strip for 6V LED. Can test individual, series combination or the whole strip of LED. Currently tested with 13pcs x 3V series LED which shows the voltage of the unknown LED and constant current of 30mA and 50mA.
