Let’s find out if Potentiometer values make a diffence when read from an Arduino
In some Arduino projects we will end up using Potentiometers.
The potentiometer (or pot, as it is more commonly known) converts rotary or linear motion into a change of resistance that can be read by an Arduino analog pin.
But which value (ohms) should you use in your project?
Let’s find out if the Potentiometer Values have an impact when read from an Arduino.
We are using 4 Potentiometer values: 10K, 50K, 100K and 500K.
The outer pins of each Pot is connected to 5V and Ground from the UNO through a breadboard.
Each Pot center (or Signal) pin, is connected to an Analog pin (A0-A3).
The sketch used to test is using the serial monitor to display the resulting values of each potentiometer values.
Since the Arduino is doing an Analog to Digital conversion, the results will be between 0-1023.
As always please have a look at the tutorial video for more information.
Copy the above Sketch code in your Arduino IDE software to program your Arduino.
