Arduino to 9-segment display

Hello Guys,

I hope you all are doing well.

I have got a 9-segment display 16-pin 4-digits that should be hooked up to the digital outputs of the Arduino Uno, The thing is, I have no idea how this 9-segments works due to the 2 additional segments and the unavailability of the datasheet or pin-out.

If you have had any prior experience with it or have an idea how I can work it out, please do not hesitate to contribute to this thread.

Thanks a lot.

Connect power (current limited) to random pins and see what happens…
