I watched the video tutorial of Dj on the radar scan and how to hook it up, I noticed he said always remember, negative is always in the center, did he make a mistake when he said that, or was that a different board? Also, I did that exact setup and I can't get my tamiya tank to respond(also, I set the settings real close to his), the servo scans like it's supposed to but it will not stop when it gets near anything, I put it on my bench on top of a stand so the tracks can run free and I would wave my hand in front of it and got absolutely no response, am I doing anything wrong? Please don't tell me I have a bad board.
Ground is always towards the center of the board. If looking at the board and the digital ports are running down the right of the board then the left hand pins are ground.
Connections to the sensor are; Cable 1 Ground to Ground VCC to VCC Signal to Trig Cable 2 Signal to Echo
Like this;
Be aware that the ping sensor is not good for all objects. A combination of ultra sonic and infra red may be required. I believe ultra sonic doesn't work good with black furniture.
Yes, did you watch that video I'm talking about? The diagram you have here is what I mean, the neg is on the left so pos is always in the center most of the times, right.and while your here, tell me , what are these wires that are included for look at the one end, it's a male plug encased and then a female on the other end, what is that intended for?
I went to collision detection and tried that too to no avail, what do you thing the problem is?
Those wires are for soldering to the sensor. Cut off the female end and solder the wires to the sensor, leaving th emale end to plug on to the EZ-B
oh, ok, thanks again
one more quick question, I have the rover from brookstone, I can operate that from my ARC software through my http right?, I mean the board doesnt have to be attached to the rover does it?
No connection from rover to board is needed. It connects through the WiFi.
