I am not using potentiometer like most video or print online. I am using bike grip/hall throttle, its range is 0.8V to 4.3V.
[0V = 000 ADC value] [5V = 255 ADC value]
[0.8V = 000 ADC value] [4.3V = 255 ADC value]
What ADC do I need ??? How do I wire???
NOTE: Before leaving comment...the video I reference below shows the author achieving 2V-3V (start video at 2:46). I want 0.8V to 4.3V. If you don't have people skills or can't answer my question...please don't leave comments... I am not as smart as some of you.
[ My research so far ]:
(1) How to use Differential Voltage Input ADC's
- Author uses ic chip ADC0831
- Video includes schematic
- Start video at 2:46 !! https://www.youtube.com/watch?v=4wT6nRqV7Vc&t=117s
(2) What is a differential ADC?
Forum quote/Peter Gibson:
A differential ADC shifts the lower reference from 0V to some other value - either a user input - - - on a second analog input, or a internal reference. What is a differential ADC?
