436  Using Arduino / General Electronics / Breakout Board help on: May 07, 2013, 08:13:09 pm
Would this breakout board work for the sn754410?

Thanks!

Thanks pito!

I did not know that if the robot was moving at the same speed it would not inter fear with the readings. Problem solved!

I would love to help you but I need some more info. To start with please give us what motor driver you are using, what type of Arduino you are using, and what type of power supply you are using.

Catford,  I would like to help you but I don't know anything about rc helicopters. Try starting a new post and other members will weigh in.



Groundfungus, I do need the sensor to be accurate while the robot is moving. Do you have any suggestions as to what I should use?


Thanks!

Is their any one you recommend? I was looking at spark fun and they seem to have a lot of choices! I would prefer something really simple to program and cheap in price.

Also, the robot will be moving up the hill when the sensor is reading.


Thanks!

Hello,

I'm building a robot and I was wondering what sensor I need to sense how steep of an incline my robot is traveling up.

Links would be great!

Thanks for all the help! I will probably buy both the sensors and the heat shields just for fun!

Thanks!

Also,

If you can't get those tiles anymore does anybody ells have other ideas on how to heat proof the project box or the wire, if it can be run a few feat.


Thanks!

I thought their was a limit to how long you could run a wire? Thats why I thought the Arduino had to be close by. Also, I think it would be easier to heat proof the project box then to try and heat proof the wire.

As rrobtillaart said where do you get those tiles?

I don't know if this is the right place to post but I think it should work smiley

My Arduino will be inclosed in a project box, measuring the temperature of a fire in a fire pit. It will be directly under the fire so i know it will probably get hot enough to melt the Arduino. What could I use to insulate the project box to keep the Arduino at a reasonable temperature?

Thanks!

Hello,

I'm also looking for a way to make a 3d design of a robot before I build it. However, I don't need the robot to function. Do you know of any free software?

Kind of off topic but I figured i would show you this video. It is an example of using colors to detect position.

448  Using Arduino / Audio / Sound Recognition on: April 19, 2013, 07:58:24 pm
Hello, I would like to know if it is possible to have the Arduino recognize different sounds and react to them. I would be using a surround sound system to play the sounds off of a cd to start with. So I would just use one set of wires that would normally be sent to a speaker. What hardware would I need to use to "teach" the Arduino to recognize a sound(S) and react to it? Also how hard would the programing be?

Thanks!

I would use this sensor…

450  Using Arduino / Sensors / Help Needed ASAP on: March 15, 2013, 08:13:34 pm
Hello, I need help asap because I have a competition tomorrow morning. I have a light sensor and when nothing is over it the analog value  is about 110. When something crosses over it the reading jumps to about 1020. I got my Arduino set up today and the value was  1021-1022 and when something crosses over it the value stays at 1022. I have no idea why and I will have only 30min tomorrow to fix it. I have checked all the wires and they seem to be in place. And all the other sensors are working one of which is an identical sensor. Any suggestions you have for me would be greatly appreciated. Also the program did not change and the lighting seems to about the same as my room.
