Hi friends, I have a problem with getting voltge readout from analog pins in Arduino Uno. I have two TCST1103 sensors connected to those inputs (A3 and A4). Their behaviour is simple and can be checked by measuring a voltage on 100 ohm grounded resistor. Of course that GND is connected to arduino's…

[image] jwut: pinMode(A3, INPUT_PULLUP); // sensor 0 The following diagram (Fig-1) will help you to understand that it is not possible (and also not needed) to connect internal-pull-up resistor (Rip) when using A3-line (A4) as an analog channel for the internal ADC. Moreover, while executing…
