so obviously im new and I need help to use a GitHub repository.

[06GTODriver]

so obviously im new to this raspberry pi. and im looking to make scales for my car. I found the git hub thing i think I want to use https://github.com/jenkinsracing/open-race-scale, but I have no idea where I need to top this in. I tried the "hello world" thing and I couldn't even get that to work.

I keep seeing people talk about typing in this sudo thing, and there's so many items on the git hub posted above... how do I get it all to work together. I have the hx711 code then the app code and lots more....please help

Maybe the best approach would be to ask the developer/maintainer of this project for advice about how to deploy it, using their GitHub account to get in touch, here:
https://github.com/jenkinsracing/open-race-scale/issues


I note that the README files contain words like 'prototype' and 'proof of concept' - perhaps this project is offered as a basis for further development, rather than being something that is ready for 'cut and paste'?

Do you have the hardware skills to produce the customized interface boards?

well maybe someone can help me. im trying to run 4 load cells with on pi using 4 hx711 sensors. all will give individual readings and for right no im not looking for it to do any math (That will come later). but like a said. I know the first thing I need to do is get the hx711 program but like I said I don't even know where to input the language

[06GTODriver]

alright lets start over. i think my problem I may be trying to bite off more than I can chew since im tryin to get 4 load cells going...trying to use 4 hx711's etc.
so moving on

I have an air pressure sensor ([url]https://www.banggood.com/Pressure-Trans ... use=CN/url]. I currently have to certify pressure gauges at work. unfortunately all the gauges require something different and this can basically cure all my problems. some of my gauges are in feet of sea water, some are in mmHg, psi, bar etc. and I think this may a decent place for me to start.

this is what I have so far,

(hopefully y'all can see it). is this a decent start?? the sensor will only be and input to the pi, and my idea is to hopefully have a GUI where all the displays will be shown at once instead of having to change code in-between each gauge being tested.

If you are in over your head and floundering my non-technical advice would be to source your components from somewhere that will provide documentation and support.


The only relevant detail I can see on the product page you linked is "Output Voltage DC 0.5-4.5 V"

My guess is that this means it is an analogue device.

There is no model of Raspberry Pi board that has analogue inputs at the time of writing.

So to use this sensor you will probably need to equip your RPi with external Analogue-to-Digital Conversion (ADC).

The gpiozero Python library has support for a common range of ADC chips compatible with Raspberry Pi boards.
