I am at my wits end and about to sell all my Arduino bits and pieces. I recently purchase the 3 items in the attached image. The top 4x7 segment display is what I am having problems with. My display is soldered onto the middle backpack. The bottom image is an Arduino Nano clone.
Can any one advise how to connect my display as it doesn't have the four terminals that the top display has? I have tried it in a breadboard, and selected what I believed were the correct header pins, but nothing worked. Which would be the correct header pins?
The project is a model train speedometer.
How do I test the display to make sure it's working?
