WebMay 6, 2024 · if 5v on the VCC --> 512 (1024 2.5/5) read when 2.5v on the analog pin. If 4.64v on the VCC --> 551 (1024 2.5/4.64) read when 2.5v on the analog pin which is was I am just getting. Solution: 1- Power arduino with 7v to raw pin or 5v direct to VCC pin. 2- Make the calculations considering I get 4.64v where it should be 5v Both works fine. WebNov 5, 2024 · \$\begingroup\$ Either build a clamping input circuit, or put an MCU with a 10-bit ADC on the input side and feed a serial stream through an optoisolator into a pi. Or just decide that a pi itself is cheap (and itself ultimately quite unreliable given the SD card) and consider the whole thing to be a sacrificial component in the overall system.
