Hello everyone!I am a robotics engineer based in London and I have interest in sensing and electronics. As a part of a personal project, I want to design my own EEG setup (potentially to control a rob...
The ACS712 outputs a voltage from 0-5V and the ESP32 ADC reads from 0 to 3.3V using 1.1V as vref. There is a voltage divider already to reduce the 5V to 3.3 range.The problem is: voltage drops on the ...
