I make something for Optical Product with Arduino. But, My Arduino has a Problem when it works with ULN2003A and FND module. ULN2003A is used to run relay, FND module is used to display the state of relay. I use Arduino with 12V/1.5A DC Adapter and the relay consume 88mW The Problem is My Arduino…

My Arduino Uno has Problem when works with ULN2003a Module and 7-segment Module

"FND module" What is that? Is it the same as "7-segment module" ?

Please provide full details on all the hardware you mention, we need to know this.
