Hi , I have a small project and I just want to display the voltage of a potentiometer on a small 5*7 LED matrix. I tried to compile different codes but the the LEDs just keep blinking and don't display numbers but serial serial monitor in arduino displays the reading. Can anyone help with necessary code and connections?
Yes I'm sure we can.
Post a schematic (hand drawn will do fine) or a well focussed close up picture (as long as your wiring is neat), and your sketch so far (be sure to use code tags). Also a link to the details of those displays.

Thanks a lot for your response , here are pictures for the connections. I hope they are clear enough.
No, I am sorry. We cannot help you using those pictures. Your wiring is like a plate of spaghetti. Please re-read my previous post and follow all the suggestions. Then we will try again.
