Configuring the Voltage Divider

← Older revision		Revision as of 16:20, 26 July 2012
Line 68:		Line 68:
	Why is adjusting the resistance important? The Analog Input can measure a voltage between 0V and 5V. The analog measurement is represented in the software as a value between 0 and 1000,so a sensor value of 1 unit represents a voltage of approximately 5 millivolts. When using variable resistance devices a voltage divider is commonly used to measure the changing resistance. The two resistors in the divider form a voltage, based on the ratio between them. This voltage is then measured by the Analog Input. To optimize the voltage divider to meet your need you have to adjust the fixed resistance to match the characteristics of your chosen sensor. To adjust the resistance on the Voltage Divider, simply turn the screw on the potentiometer clockwise to decrease the resistance and counterclockwise to increase it. You get between 900 ohm to 1000 ohm change in resistance per revolution. First, adjust the resistance for no stimuli on your sensor and then apply maximum stimuli and make sure that Sensor Value stays within a range that gives you expectable resolution. At the extremes (<50, >950), a very large change in stimuli (and therefore change in the resistance) produces only a small change in Sensor Value. Keep adjusting until you get a range you are happy with.		Why is adjusting the resistance important? The Analog Input can measure a voltage between 0V and 5V.
