LDR vs Ir Phototransistor

Hi  Everyone

I'm doing research for my first bot from scratch. I was hoping someone could point me to a good source of info on the advatages/disavantages of using LED & LDR vs Ir with Phototransistor for proximity sensors.

My basic goal for them is to have an edge detector in each corner and a line following array. I thought the LDRs would a simple and cheap approach but was surprised to see how cheap this Ir LED & Phototrasistor set was.

ATTiny programming

I saw this link about programming ATTiny:


is it possible to make an ATTiny board to replace the Uno for programming other ATTiny chips?

they appear to have the same pins that are used by the Uno; 'SCK, MISO, MOSI'...


Please dont laugh this little guy off the planet. He was a very old robot kit Called Mr. Technoman I'll upload a picture of the box later for fun. The old robot was … Read more

First Robot Plan

I'm about to start my first robot project so i thought i would document my progress, I don't imagine anyone else will be interested so i'm mainly doing this so i have a record.Controller PCB

For a project at Uni I have made a Wireless controller and a motor driver PCBs. They both include a built in arduino and communicate via XBees. I get to keep the PCBs from the project and have bought the ATmega328 chips, XBees and a chassis as these are the parts we had to return.

I plan to use this as a base for my robot and add more features as and when i can.

How to get an Arduino Uno + Rover 5 up and running


I first touched an Arduino last November.  Come Christmas, Santa left a 4-motor Rover 5 under the tree for me and the kids.  As far as I can tell I can't just hook this up to an arduino board, but need to have additional controllers.  What is the best way of doing this?

[I have an Arduino Uno.  Will the Rover 5 work with a Uno?]

What's the easiest way to get it running? Should I be buying a Dagu 4 channel motor controller?  Would that get me there? Someone mentioned the Pololu TB6612FNG Dual Motor Driver Carrier.


RAD 2.0 Schematic?

Does anyone have a schematic or diagram outlining the electrical components for a RAD 2.0?
