Quote from: mandu on October 14, 2023, 10:53:46 PMThe picture you posted shows common cathode (connected to the -ve).Thanks for your help.
The other two are for red or green (or yellow if you power both) goes to the +ve
The limiting resistor may be 1 if wired on the cathode or 2 nos. if wired from anodes.
