How do you connect a SRF005 to an Arduino MEGA 1280

I need help on connecting a srf005 (the blue one) to an Arduino MEGA 1280

You can use this image as a guide.

I want the connection for the srf005 using only three pins. :) (The one where you connect the mode pin to ground)

Thanks,

Maxsonar ez1 vs srf05 vs parallax ping

Hi

I'm new to this forum and i would like to know a few things.

Which one of the following ultrasonic rangefinders do you prefer.

I know that the ez module is designed for indoor environments but i would like to use my robot outdoors

as well,do the ping and the srf05 would outdoors as well.

My robot is going to be a basic obstacle avoiding robot for otudoor and indoor use.

I know the ez is accurate to about 1 inch,what about the accuracies ofthe srf05 and ping but this is really not going to

Several SRF05 sharing the same picaxe's trigger output pin ?

Hi guys,

First of all, since this is my first topic here, I want to thank you all for this great community. I have learned a lot and I have just finished my first robot thanks to you :) I am now thinking about the next one, and here comes the question !

Altered 'Start Here Bot' Code

Im trying to run my start here bot that is has a tamiya twin gearbox and SRF05 instead of the IR sensor on it. All the components work, just not together. I wrote my code (most copied from frits) but my robot just goes forward and back, sometimes sideways about 2 centimetres. Can you post anything wrong in the code that may help to fix this problem

No response from SRF05!

Hello, I am trying to connect a SRF05 to my 28x1 PICAXE starterkit.

 Using the "start here" guide and the How to connect SRF05 to Picaxe 28 pin Project board
I am able to make the SRF05 LED flash like the guide says it should, however I am not able to receive any input in debug.

I have connected every wire like in the picture and I am only using the program provided. 

How to connect SRF05 with a ribbon cable? (I'm not sure either!)

Well, I was browsing like 100s of robots on this website, many of which use the SRF05 (SRF005) and I see that HEAPS ( I did that on purpose) of them use ribbon cables (which are included when you buy this picaxe 28 pin project board. It seems much neater and easier. It would make things easier and save money. Can any1 tell me how to do this?

Zen Master

I'm building a robot with many different voltages here.

I have managed to avoid voltage regulation by cheating, I run the motors that are rated for 4.5 volts at 6 volts from a RC NiCd battery, and I use an RC Electronic Speed Controller that can give 5 volts to the RC receiver, the wireless camera and the Picaxe. I feared that this might be a problem and turned to the all knowing LMR forums for help. And help I got...
