ultrasonic sensors

bumble88

Hi,

I'm using the ultrasonic sensors·to connect·its 3 pins·to the Board of Education·development board. Ive used the programming code available from the parallax·website. When I·switch on switch number (1) and run the basic stamp editor, it showed me·the distance·values.· However, when I switch on switch number (2), there are·absolutely no value. I thought switch number (2) is to power everything.

Please help because I need to use switch number (2) to run the servo controller.· By the way, I doing the hexapod walking robot. Thank you.

Hope you have not connected the·ultasonic & servo controller on the same I/O.

Hi,

Ive connected the·ultrasonic sensors·GND pin to Vss, the 5V pin connects to Vdd and the SIG pin connects to I/O pin 15. When I switch on switch (1), it shows me some readings where as switch (2), there is absolutely nothing.

Nope, I did not connect the ultrasonic sensor and the servo controller on the same I/O.

Hello,

·· Do you have anything plugged into the servo headers on the BOE?· There are 4 of them there.· If so, which ones are you using?· One other thing to consider…When you move the switch to position 2 does the power LED dim at all?
