1. Make the hardware connections.
The common cathode LED (3641 AS) display requires the use of 4 220 Ω resistors to be used with an Arduino UNO-compatible development board. Being a common cathode, the resistors will be mounted on the pins that select the digits.
To deduce the significance of each pin, see the attached images below:
Connecting to a development board is easy because each pin has to be connected to a digital pin. A connection scheme would be the following:
2. Load the code on the development board.
If you do not have the segment display experience, you can download a library specifically created for this component. This is called "SevSeg" and can be downloaded from the Arduino IDE development environment, following the following steps: open SKETCH> INCLUDE LIBRARY> MANAGE LIBRARIES and search for "SevSeg". To load an example, go to EXAMPLES > SevSeg and select one of the examples. You also need to make sure that the declared pins match the connections made and that the corresponding screen type ("COMMON_CATHODE") is selected.
