I'm 21, and i'm at the end of my master's degree in engineering. I'm new here, because I'm specialising in metal works lol.
I never was that good in coding but for the sake of a project I jumped into it.
So, I have a project, where I'm supposed to make resistivity sensors for steel in concrete, so we can know when they rust. That's the overall aim of the project.
Before, they had to plug a wire into each sensor. Now we want to have to plug it once, and then choose which sensor we are talking to. Sweet.
So what I understand (Arduinowise) is that I have to burn a bootloader on many target boards, in my case a Nano, from the same programmer, Uno.
Then using a breadboard, I'll connect many targets.
So the external device will ask my Uno to ask the Nano X to give its values.
Using Avrdudess I've flashed the blink code (converted in .hex with IDE) to my programmer and my target answers successfully. So I did the same for my measurement code, but I don't know how to choose 1 target among others.. That's were I'm stuck.
Is it even possible to do what I'm talking about ? I have a lot of codes from older students and me so if you want to see something let me know, it's the overall process that I'm not sure about. I'm mixing everything, optiboot, avr...
Thanks for your time.
