Webfrom my experience the common pin is usually somewhere in the "middle" of the other pins, but you'd have to post the datasheet to be sure. If it says pin 13 on the instructions and the diagram has the pin layout, connect 5v to pin 13. You can try and ground/power different pins until you find the common anode. Just don't forget the resistor. WebJan 22, 2024 · Common Anode – 0 will make an LED glow. Common Cathode – 1 will make an LED glow. Common Anode Method : Here we are using a common anode display therefore 0 logic is needed to activate the segment. Suppose to display number 9 at the seven-segment display, therefore the segments F, G, B, A, C, and D have to be activated.
