Title: 10k Potentiometer fast question
Post by: Dellyjoe on June 25, 2013, 05:36:35 pm
hello everyone im just about done my project i have two things to wire up and i don't know which two are the cold and which one is the hot.


i know for photometers you have two cold and one hot.

here is the data sheet that i found but it doesn't tell me anything.

Centre pin will be the wiper  :-+

If you want increasing Vout (centre pin) moving in a clockwise direction, looking from the front, Vlow goes to the left pin, Vout ( with respect to the left pin, Vlow ) comes from the middle pin and Vhigh goes to the right pin


If you want decreasing Vout (centre pin) moving in a clockwise direction, looking from the front, Vhigh goes to the left pin, Vout ( with respect to the left pin. Vhigh ) comes from the middle pin and Vlow goes to the right pin
