I have just receivd my spark core + a small digital scale i ordered from ebay(which i loved tearing appart down to its electronics).
My basic goal is just to get a read from the scale to the spark app.
I only have little knowledge on cuircuits and programming but hopefully with your help i might be able to make it happen.
All i know about the scale is that it’s range is 1gr-5kg and work on two 1.5 volt battery. I understood i need an amplifier. how do i choose the right one? What are the calculations i need to do?
Do i need any other resistors/capacitors in my cuircit? if so, why? and how do i choose one?
Any help will be really appreciated…
Thank you so very much.
