I have connected MB1040 sonar to A0 pin of apm 2.6 board as shown in the following link

I have selected Analog in the initial setup and there are no values being shown...

i also tried giving the signal pin 5 V separately it just doesn't seem to work
Help me!

Your input pin is set to -1. Set it to 0. You may also need to change the scaling. For my MB1240, I set it to 2.04.
