7-segment Display : Working, Types, Interfacing & Its Applications

A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic CCD for Cathode Current Departs. A conventional current describes the direction in which positive charges move. Electrons have a negative electrical charge, so the movement of electrons is opposite to that of the conventional current flow. Con… WebThe 4511 display driver IC requires a common-cathode 7-segment display unit, which is what is used here. So, we must connect the cathode connection to the ground.
