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

 

Do you want to make a variable power supply with a battery, or are you trying to monitor the battery load?

A variable power supply. I've made one that is analog where u turn a knob to adjust the output but I'm trying to figure out how to make one that is digital.

 

Well you need a micro to do the output in steps, like this example using a pic/Tiny and a Lm350 regulator,

or a CD4017, Lm317 http://kitsnspares.com/admin/pdffiles/Variable Power Supply.pdf

i personally would make an analogue psu, with a digital readout...

 

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.

Perfect. Exactly what I needed. Thanks m8
