Hmc5883l Triple Axis Magnetometer Help

Hi So finally I got may HMC5883L Triple Axis Magnetometer through. But I cant seem to get it working and there doesnt seem to be any reference to it only a dual axis one. All connections were obvious so I know they are right. Its connected to the 3.3v not 5v. I cant say much more than that. I tried using the dual axis options but it only returns a...

Accelerometer And Gyro Confusion

I think I may have got my self a little confused. Whats the difference between an accelerometer and a gyro? Does an accelerometer return the movement of each angle or the angle itself?

Audio Transfer

Can audio be passed to and from the EZ-B? I need a mic mounted directly onto the robot as well as a speaker but with no wires between the robot and pc. Ive found wireless mics and speakers to either be really low quality and/or too expensive. hat being said, I am thinking of using SmartVR with the EZ-B. Has anyone had any experience with this at...

Standalone App

I was wondering if it was possible to build a standalone android app with the ARC ?

Ezb Dlls For Net Framework 2

I need the same dlls for the ez robot but that can be used in a net 2 framework. The only functions I need are for servo operations. Is there one out there or can anyone help.

Localised Sound

Inertial Sensor?

Hi I think Ive got myself a little confused. Whats the difference between an accelerometer and an inertial sensor? Or are they the same thing?

I2c Query

Hi folks, I have another I2C query. Ive learned now that I2C devices have addresses meaning multiple devices can be attached. This is awesome of course. My question is now, if I had, say 2 accelerometers of the same type attached, can these be accessed separately? Am I correct in thinking that they would have the same address code? For scripting I...

Expanding Digitalports

I was wondering if anyone had a simple solution for adding more digital connections to the controller. One idea I had was to link an arduino to it via i2c, although I dont know where to start to do that. I need to increase the connections by about 6 ( making 26 ) minimum.

Android And Ios

I was wondering if it as possible to write programs with the SDK for use directly on an I phone, ipod etc or android device. so the device connects to the robot directly and doesnt use a pc at all

Analog Or Digital Servo

Hi This may sound like a daft question, but Ive just noticed that there are analogue and digital servos Does it matter which I use?

3D Position

Hi This is difficult to ask. im in need of some kind of beacon to return a 3d position of the robot in relation to a fixed point. infrared not ideal unless it can move around objects/through walls etc beyond this im not sure how else to explain. I once saw something to do with VR about it but cant remember where.

A Question Of Torque

I was wondering if someone could give me a little clarity here. If using gears to reduce a servos / motors rotation by 50%, will that increase its torque per cm? Im going to be using a 40kg Servo and I am going to reduce its rotation from 210 degrees to 105.

Is It Falling?

Ive just ordered a MMA7455 Accelerometer from good old ebay. This is going to sound a little daft but im going to need a little guidance. Im going to be using it so I know what angle my bot is at but how can I use it to tell if the robot has been pushed or is falling? any advise on the subject would be greatly appreciated and I cant really say any...

This is gonna sound silly but Ive had to reinstall windows and Ive forgot what the Bluetooth keycode is. I never changed can someone advise?

Help With Power

Im wondering what kind of 12v batteries to get and to help my understanding id like some help understand the amps. My motors use a current of 1.4A ( 20 of them ) and the battery Im looking at says 12Ah. Im also going to be using it to connect the EZ controller. Can some one help explain what this means please. I was also going to add a solar...

Control Ez Board Via Serialport

Is there a way to controll the ez board via c#s system.io.ports functions without calling the ez sdk or using the ez robot dlls at all.

Serialport To Operate Ez Board

Is there a way to controll the ez board via c#s system.io.ports functions without calling the ez sdk or using the ez robot dlls at all.

Although I dont know much about them. Heres what Id like to know about them: . can they be powered from a battery of some kind . can software written on c# be...

2.5 Amp Motor Controller

Just a very quick question about the 2.5 Amp Motor Controller. I see that 2 motors can be connected to it but can the be controlled independently or not?

Switches And Resistors

Is it possible to add a push button switch, even going as basic as two wires that connect via pushing. Also how do I add a variable resistor. Also will a basic dimmer switch work as a variable resistor? I know these may seem like really daft questions but it helps me alot. Can someone please talk me through it.

Additional Hardware Help

Im just wondering if anyone knows if these can be connected to the ezb board: http://www.robot-electronics.co.uk/htm/tsa01.htm http://proto-pic.co.uk/tmp36-temperature-sensor/ http://www.robot-electronics.co.uk/htm/cmps3tech.htm http://www.robot-electronics.co.uk/datasheets/uCAM-DS-rev4.pdf...

Compass, Gps

Can anyone advise on some cheap addons for me to add GPS, compass and a gyro to the board

10 Kg Servo

Just a quick question. What does the 10 kg bit mean? Does it mean they can push a weight of 10 kg?

Standard Ultra Sonic Sensor

Hi This is my second post and now I need a little help with the ultra sonic sensor. I looked at the video from dj but I couldnt see the actual way to hook up the wires to the sensor. Would it be possible for someone to describe in detail the best way to do it. Some good images would be great. Thanking you guys in advance. Jay
