Hi, 

I need to get a code for a project I am doing. I am using an Elegoo Mega, an ir module with combined photodiode and led and hopefully I can display rpm on the LCD display. I have connected up the four wires for the LCD but no data is shown on screen. I would very much appreciate any help with this

Without seeing your wiring and current code how can anyone help?

Have you tried sending some status/debug prints to the Serial Monitor?  You could have problems with any number of things....loading the sketch to begin with, reading the IR beam break you are trying to measure, getting output to the LCD...or any number of wiring or code issues...

Could you post a schematic, photo, or the sketch code?
