Frequently Asked Questions
In a common anode display, all the LED anodes are connected together to the common pin, and the individual segments are controlled by grounding their cathodes. In a common cathode display, all cathodes are tied together, and segments are controlled through the anodes.
Yes, this display can be directly interfaced with Arduino and other microcontrollers, either by using current-limiting resistors or with driver ICs such as the 74HC595 or MAX7219
Yes, resistors are recommended to limit current and prevent LED damage. Typically, 220Ω – 470Ω resistors are used depending on supply voltage.
