Use OpAmp like I did here: http://www.electronoobs.com/eng_circuitos_tut19_sch1.php

Or maybe just a pullup like this:

thank you very much for reply, i tried using non inverting amp in LM328,Did not worked, Pull up resistor is working. Do i have to modify program?

please modify program for 120 degree sensor position for BLDC motor from tutorial of "Sensored ESC"?

arduino is not giving 5v in at output pin, it is giving only 4v becouse of that transistor is not turning on. What should I do?

 i am using BLDC motor in my final year project, i am totally dependent on this tutorial so please help
