How to recognize positive terminal of LED if both terminal are same in length
There is column wise connection on breadboard, But while showing use of push button, in live setup, LED and resistor are placed side by side.
How do we identify either it is A pin or B pin ?
Is two COM pins are internally connected ?
What is the purpose of resistor in connection of seven segment display and how to connect the resistor. How to identify common anode and common cathode Seven Segment displays.
how to identify the seven segment display as common cathode and common anode?how to identify the tri color led as common anode and common cathode?
is that necessary to connect the both com with the ground in common cathode ??
