When resistors are connected in series, the total voltage (or potential difference ... When resistors are connected in parallel, the supply current is equal to the sum of the currents through ...

The two resistors may have fixed values or one may be an LDR, a thermistor or other input device. The supply voltage is divided in the ratio of the resistances in the voltage divider. For the ...

Normally you’d throw in some resistors to form different voltage dividers depending on which key is pressed, and read the resulting voltage off of a voltage divider with an ADC. But that means ...
