Hi all. Working on a project with my dad and we need a little help. Looking to build a module that can regulate wattage or volt output with a digital display that shows battery gauge and ohm readout. Sounds complicated and I realize there will be a bit of programing involved. Any and all help is greatly appreciated. Thank you in advance

Close enough but not quite there yet. You have to tell us what you are trying to do.
Are you trying to display the voltage of a battery and the current drawn?
You can do that with a voltmeter and an ammeter, analog or digital. No programming required.

That sounds like you need a voltage regulator, a digital display, some way to interpret battery voltage, and what do you want to read the ohms of?

Building a homemade vaporizer modbox. Basically a box that has a battery and a firing button. The regulator would have an output to a 5 10 connector and the readout would have two buttons that adjust the volt/wattage output to the 5 10 connector. The readout should display watts/volts, battery life, and ohms. Battery would have a charging port

Then what you need is a variable voltage power supply with current limit adjustment.

Voltage and current are not independent. You set the voltage. The current will be dependent on the load.
You set a current limit. If the current limit is reached then the voltage will be reduced to accommodate that current.
