Hello everyone!

Calculating Resistor Bridge


Well, I messed around with a lot of resistor combinations, and got really frusterated with sorting through my resistor box looking for all these different values. Instead, I grabbed a pot. I got this one --its a 15 turn, 10k trimmer. I did some preliminary tests and I would love if someone could check my math and calculate the current it is going to draw. Following is the values read with a measure thingie on either "side" of the center pin of the pot.

You GOTTA see this Turtle Robot!!

This is amazing!!


My Chinese partner is talking to this guy about sourcing the parts or a kit for this robot...

Anyone seen / done something like this?

Mounting brackets for SRF05 (Open letter to Jack / DAGU)

SRF05 is still IMHO the best low-cost distance sensor.

And there is still no good / smart / fancy / easy / pro / cheap way to mount the darn thing on a turning neck / servo / front..

We now have a good contact to DAGU from China who makes cheap and cool robot-stuff.

So.. I thought.. Why don't we make some suggestions to how we would like such a mounting thing(ey) shaped and made? And then ask Jack from DAGU if he could start producing it?

This was my idea.. and now I need your help and ideas towards the design :)

Nothing works. Where did I go wrong?

I have tried to build my robot according to the schematics below, but it is not working. Where did I go wrong??

Have fun with it.

Servo'd Bluetooth'd Tamiya Bulldozer Robot


Hey cats. I spent the past 2 days writing a new design/control app for the ez-b and decided to make a new robot as a test platform. so yesterday i noticed i had a few of these bulldozer kits lying around, but i find them annoying due to the DC motor gearbox. A few years ago i started using modified servos instead of dc motors on the bulldozer kit. I get the odd email asking how i did that...

Soooooooooooo, i coupled the two together. A video showing how to build a servo driven tamiya bulldozer and the ez-builder

360 Degree Laser Scanner Development Kit (RPLIDAR)

Some years ago we were dreaming of a nice and cool and also precise way to map a room or the surroundings of a robot. Today it's coming affordable and available not only for high funded institutions but for all the hobbyists and robot builders.

Multiple Array in Arduino

Happy new year LMR,

I am trying to modify the buzzer code from arduino sample. I wanna try to keep it simple and easy to call a function to manage different tones. For example:


Self-transforming robot

Hello everybody!

Check out this amazing self-transforming robot if you have a couple of minutes to spare. It was designed, built, and programmed by Muhammed Hasan Shariq at Heriot-Watt University, Dubai campus.

Help me choose a Arduino microcontroller


Hi guys looking for a bit of advice , hoping to buy a few bits and pieces shortly, and after checking out various places feel YourDino shop is going to be the place for me to shop from.

Bootloader burning problem


I've been trying to bootload an AtMega328 for a while now but the chip simply isn't complying.I've followed the instructions given on this link http://arduino.cc/en/Tutorial/ArduinoToBreadboard and not using the minimal configuration.

 I've tried it several times and rechecked pin connections and they all seem fine.Btw, I'm using arduino duemilanove as an isp .Everytime i'm getting an error:

protocol error,expect=0x14, resp=0x51
