Dear Friends
I am making the PID line follower robot with LPC1768 cortex-m3.Also I am using NCY70 IR sensor. I’ve become confused about circuit of IR sensor for connecting it to ADC of my micro. I’ve seen a variable resistor on most of the circuit diagrams but when I look at the ready IR sensor array from special company, I can’t see any variable resistor in it. Can anyone tell me how they remove these variable resistors in circuit diagram?
This is the pure circuit in most of websites: http://daneshnameh.roshd.ir/mavara/img/daneshnameh_up/9/97/esquemaCNY70.gif
However this is the link of that company makes it in package: http://www.pololu.com/catalog/product/960
Lastly, if you could tell me clear & complete circuit scheme I would be thankful, because i want to make PCB board of that![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
