This circuit is used to create a simple "edgebot" sumo robot. Being an edgebot refers that it will repeat the same backup/turn/go forward action when it's single edge sensor detects the edge of the ring. This version of the circuit is quite simple, and always turns the same way.
Seeeeeed Stuff

HELLO EVERYONE, AND WELCOME TO THIS WEEK'S EDITION OF STUFF THAT'S NEW.
But before we get started, how about some light-hearted entertainment, yes? Chances are you've heard of the Toronto International Film Festival. It has something to do with those fancy moving pictures that seem to be all the rage these days. You might recognize them by their other name, "talking pictures" (or just "talkies"). In any case, this year the folks at TIFF Kids are running the Digiplayspace activity center for kids, which includes lots of electronics technology. And among this is a bunch of good ol' Solarbotics stuff. Check out a video here:
Alright, onto new product shenanigans. We got a small collection/fistful/smattering of stuff for you, particularly with some fresh stock from Seeed Studio.

DSO Quad - 4 Channel Digital Storage Oscilloscope $199.00 Whaaat? You have no 'scope? You need a 'scope. The Seeed Studio DSO Quad portable Oscilloscope is the one you want to strap to your forearm and show off, saying "NO, this is no MP3 player - this is my OSCILLOSCOPE! YOU dance; I'll measure the RMS!". Well, it could happen... |
 |
TRS (3.5mm) to BNC probe converter (DSO nano compatible) $1.50 Being so incredibly small, tidy and useful, the DSO nano has to use small non-standard jacks for the test leads. You want to connect it to standard leads? Here's the converter! |
 |
SeeedStudio Music Shield $27.50 Yes, there are other music/mp3 shields out there, but SEEED Studio does it again with a very complete unit! |
 |
Relay Shield $20.00 You want to move power? We've got the SeeedStudio Relay Shield that'll let the milliamperes of an Arduino-compatible board to control up to 35VDC 70W on 4 seperate channels! |
 |
Adafruit RGB 16x2 LCD Shield Kit (POSITIVE Display; RGB text on black) $25.95 You want shiny? Pretty? Informative? What is this, a 6pm news-anchor? NO! It's the Adafruit 16x2 Character LCD Shield, in red/green/blue POSITIVE display (the text is colored, not the background). |
 |
Tamiya Multicore 8-conductor Cable (5m) $13.00 Tamiya makes all kinds of stuff, including this "spare part" colorful cable. |
 |
C@H 120ma 5V/3.3V Step-up/Step-down Converter $5.50 Besides having a totally fabulous part number (18888 - just say it), this tidy little package is sure to be as similarly fabulous in any design you're working on where you want some regulated power, on the cheap! |
The only problem we have with those fine folks at Seeed is their name. It just makes you want to lean on that 'e' key for a bit longer than you know you should. Seeeeeeeeeeed.
Oh, yeah. That hits the spot.
