	The 1134 ~~Switchable Voltage Divider~~ is a voltage divider with switches. The switches can be used to control which resistors are used in the voltage divider. From left to right, the resistance values (in Ohms) are 249, 820, 2.61K,8.45K, 27.4K, 91K, 300K and 1M. It is possible to have multiple switches flipped, putting the corresponding resistors in parallel.		===Resistances===

	{\|		To optimize the voltage divider to meet your needs, you have to adjust the switchable resistance to match the characteristics of your chosen variable resistor. First, adjust the resistance for no stimuli on your sensor, then apply maximum stimuli and make sure that the voltage stays within a range that gives you an acceptable resolution. The formula is most accurate at a voltage of 2.5V, with an error of 0.4%. At 0.5V and 4.5V, the error increases to approximately 1.1% and at 0.25V and 4.75V, it increases to 2.1%. As a general rule, if the voltage is over 4.5V, a lower resistance should be switched in. If the voltage is below 0.5V, a higher switch should be toggled. Continue adjusting the switches until you find an acceptable range.
