4 x 7 segment LCD display

Hi, I think I may have blown my 4 x 7 segment LCD display that I have attached to a Feather HT16K33. I am unable to get it to work on the two projects I was attempting. Can anyone help me with the most basic way of testing the display to check if it's ok? Or point me to somewhere that might be usefu...

Re: House lights for model railway

To Stryker,

Thanks for the quick reply. Is what I want to do overkill? Is there a simpler circuit I could use?
Again, thanks.

House lights for model railway

Hi! Can anyone advise what module(?) driver (?) or shield(?) I would need to create a 4xLED random on/off light for 4 houses on a HO railway set up? I would like to have between 1 - 4 house LEDs light up (only 1 LED/house). Sometimes have a random 2, 3 or all 4 LEDs light for random lengths of time....
