Smarter Life

I started with the op-amps. I put it in the non-inverting mode,  I measured the voltage at the Arduino compatible I/O header J2.  I could measure only digital voltage VDD = 3.42 volt. When the noninverting input is connected to VSS the output becomes zero. There is no in-between value. Though  I  selected 3 analog pins. I took one example for op-amp. For this also no analog output. If the pins can give only digital output then why analog pins are listed in components? Next I' ...
If you like my project vote for "A Smarter Tricopter - Yuri Tikhonov"   Good day comrades! 1. Let's start with the current situation on the construction of the tricopter's frame. In my case it consists of the following components: aluminum square tubes: 15x15x600mm and 15x15x500mm; two plates made of fiberglass; landing legs made of wooden ruler; M3 screws, M3 washers, M3 nuts; plastic clamps.   Tricopter's features are already emerging:   Originally, I planned to us ...
