map function

In this Arduino project, we will learn how to control a servo motor using a potentiometer. By reading the rotation of the potentiometer through an analog input pin, we can obtain values ranging from 0 to 1023. We will utilize these values to rotate the servo motor from 0° to 180°. First, let’s build the circuit and then proceed to write the program. Connect the power pins (5V and GND) to the + and - breadboard lines, as shown in the image below....

When working with analog input pins on an Arduino, the acquired values are typically in the range of 0 to 1023. This is because the analog read resolution is 10 bits, resulting in a range of 2^10, which is 1024. However, on certain ARM-based Arduino devices such as Arduino Zero, Arduino Due, and the Arduino MKR family, it is possible to extend the resolution to 12 bits by calling the analogReadResolution(12) function....
