Then we will first find out the ADC value according to the varying voltage using analogRead(). We will pass the ADC pin connected to the potentiometer as an argument inside it. This will be stored in the integer variable we defined previously ‘sensor_reading.’ sensor_reading = analogRead(A...
The ADC pin is reading the op-amp circuit output. and circuit is connected with the FSR sensor. Here, I have attached the picture of the Op-Amp circuit. Where FSR1 is ADC1_CH6 pin. You do not have the required permissions to view the files attached to this post. ...

i was reading the battery voltage of 12.6 in esp32 board with the adc pin34 by using the voltage divider of r1=10k and r2 =3.3 but at the 12.6 volts it was getting adc reading as 4095 but when 6.3v expected adc value is 2048 but is getting like 1800,1900 what will be the issue...
