I am a mechanical designer. I built a 3d printed tool. But don’t know how to wire it up.
The controller needs to be real small.
I have a “16-bit ratiometric sensor”.
The guy I bought it from (over 5 years ago) said it requires a 9V regulated power supply to reach full 16-bit analog ADC resolution.
It has 3-wires: + (Red); - (Black); and “Signal” (Yellow).
If it matters, the 9V Alkaline battery I used is not new.
It reads 9.05V or 9.06V on my Multi-meter (on different days).
I hooked this battery + to Red wire & - to Black wire.
Multi-meter from Yellow to Black wire reads from -2.52 to -6.57 V .
Multi-meter from Yellow to Red wire reads from +2.45 to +6.75 V.
(Each read separately) Seems very repeatable.
How do I read this with Arduino, even at 10-bit steps?
Possibly a different topic, I really want to read it in 4,000 steps. At least 2048 steps.
For now, I believe 6.5V is too much for Arduino so I haven’t wired it up.
I can read and debounce the rotary encoder and write the reading to my little 0.96" OLED screen but my ignorance is getting the better of me on this.
I hope I don’t have to spend another 2 months learning something else way over my head and I am looking for any help I can get.
