Hi, first of all I would like to say, that I am n00b, actually never studied electrotechnics.
I did one build with Arduino, but it was just LED strip and thats all.
So I would like to ask you for help me to understand to Arduino and if its even possible to do what I want to do.
Now, I have a build in my mind, but as I said I dont know much about arduino or batteries etc.
Portable Temperature and Humidity meter
I know how to connect a display, battery and BME280 modul to Arduino and got it working in Tinkercad Circuits.
You can check it trough the link if you want to.
Now I am struggling on the portable part. I mean, I can carry it because its powering from the battery, but some day I will need to take it and take out battery and charge it.
But I dont want to every time to take out the battery and get it somewhere to charge it. My idea is to take the whole box and charge it trough usb, like by PC or PowerBank.
I know i would need more parts like Linear Usb charger next I think I would need some Charger Shield to not blow up the battery.
I read few pages about charging a battery (making a charger) but I dont know if its the same what i want.
So I dont know if I can even build this, is it possible to charge battery like this ?
I think I would need a swith to turn off a display or even whole Arduino for charging, right ?
Another thing I am curious about is how long it can operate. I read that Arduino can operate moths from a coin battery. I wonder how long I could operate Arduino from 5000mAh batter with LCD display, I have hard time to figure out cunsuption of Arduino and LCD display. Maybe its stupidly obvious, but I dont understand it, but still trying to get it. I saw some SW options for sleep modes with Arduino, that could run for a long time right ?
So now you know my plan and my troubles.
If you have any knowledge you would share with me, please do, or send me somewhere else where I cand find more, like for dummies
