Analog readings on Arduino returns wrong values -


I have tried to measure the analog pin value using standard sketch available in Arduino IDE. However, when there is no relation to the PIN, it prints random values.

I have an FSR sensor connected to an analog pin with 5 V + << p>

The connection that gives you a random value is not fully expected, the pin is floating, and it can not be charged at any time, by giving random value.

Enclose analog input on the ground - this is a number near the zero (within the accuracy and noise) of the ADC).
