Step 7: Front End Work

Time for some work on the business end of Buggy. First is the IR emitter (clear) and detector (dark). Note the orientation of the long legs (picture 1). Bend them 90 degrees near the base and insert them into the board (picture 2).

Now for another sub-optimal trick. Insert the CdS cell as shown. One of the legs shares a hole with the detector (picture 3). If the don’t both fit, drill it out a bit. Try to leave some pad on the backside, but it is not critical. The leads just need to be solder together.

Resistor R3 (150 ohm) also shares a hole with the emitter (see picture 4).

Double check you’ve got the emitted and detector in the right places (I’ve switched them more than once), and solder away. See if you can do a better job than I am in picture 5!
I have an idea! What if instead of a photo resistor, you put a color sensor? And instead of changing the eye colors manually, they would change color when they "talk" to each other. That way, you could program them to use morse code! You could probably even make a handheld device that could be used to communicate with the critter! Great start! :)
what is the dimensions of the buggy and could you make it that one is the key and one is the lock and when the key comes close to the lock and they send ir to each other then the key unlocks or in my case works a relay a lcd and 2 LEDs Thanks can some one answer please
I might be making a IR lock system based on the arduino
The board is approximately 1" x 2" (25 x 50 mm). An IR lock/key is a novel application. I don't think it would take much to get the Attiny45 to operate a relay.
thanks but i was thinking of combinding a sort of pet idea with the lock key system but the one "key" can unlock like 1+ diffrent locks
and like if their was two sets like set 1:key -lock-lock-lock this key can't unlock set 2 set 2:key -lock-lock-lock this key can't unlock set 1
Now all you need to do is make a communication network for them. Network-Buggy.
Can anyone tell me if this will work to program the ATTiny44v I need to make a Buggy? It is listed in the device list but just wanted to hear someone say it was a decent thing to get.

I haven't used it myself, but yes, that is the &quot;gold standard&quot; for programming AVR chips and will do an Atttiny44.<br/><br/>If you are building Buggy to learn and have fun, why not do the same with the programmer? I built my programmer using a kit from Lady Ada, and it was only $22 (plus shipping):<br/><a rel="nofollow" href="http://www.adafruit.com/index.php?main_page=product_info&amp;cPath=16&amp;products_id=46">http://www.adafruit.com/index.php?main_page=product_info&amp;cPath=16&amp;products_id=46</a> Check out some of her other cool kits while you are there. We did the &quot;Game of Life&quot; one at the same reunion we did &quot;Buggy&quot; at.<br/>
Glad to hear it about that programmer being the "Gold Standard" for programming the AVRs. I had already ordered this before I saw the kits. Can you say impatient? I knew you could. I am also under a considerable amount of pressure to get some Buggy's into production from my quality control / product testing department. ( read: The kids ) Hope my PCb creating works out! I have ordered a Mini POV kit from Lady Ada and am considering a game of life kit as well. We have been making BlinkyBugs while we are waiting for parts to come. Those are super easy and super fun. Thanks for haveing that on your site as well! You realize my kids think you are an Electronics Superhero for creating Buggy right? They can't seem to realize the difference in the fact that I am an Electrician and not an Electronics Tech. lol
Excellent Instructable with killer explanations and parts list too!? Nicely done. This will be my first programming (does loading your program count as programming? lol ) of a chip for a project. I just ordered the programmer. Exactly what I was looking for. I can't wait to get started. KrakenFan
NICE! I know you didn't want to fuss about how to make the board, but is there a place I can find for how you did yours? thanks.
Here is a good example of the toner transfer method:<br/><br/> <a rel="nofollow" href="http://www.riccibitti.com/pcb/pcb.htm">http://www.riccibitti.com/pcb/pcb.htm</a><br/>
cool i love how they can "talk" but it would be so much cooler if they could walk or roll like soileau segusted
Nice! Made me think of a nursery rhyme my parents always told me: "Good night sleep tight, don't let the bed-bugs bite!" New version: "Good night sleep tight, don't let the LED-bugs bite!"
This would be a wonderful bot to join with a vibrobot or even better a beetlebot.
or even a muosebot.
Your images are amazingly incredible, keep up the great work! I hope to see more from you!
sorry about posting 3 times but what currency is this in?
Sorry, I forgot what an wide audience this reaches. The parts, not including the board, are about $8 USD.
You know what. That is one of the best instructables ive ever seen. It has a decent and non-violent purpose (see my other instructables and you will find out why i said this), and has a good application of technology to suit your (((*ahem*))) needs. It is a very clean instructable, and i would like to thank you for shareing it with myself and the world.
That would be soo sick if you turned them into walkers or vibrobot things they would walk around and interact!
good idea if i do end up doin this project since it is a really cool craft i may try to make it movve
you could program it that when it gets a ir singnal from another buggy they start chirping making it sound like their talking
wow you got my vote im going to try and make one
Very well planned out. Also nicely put together. Great work, with good pics.
wait....where did you get the stuff to make the pcb?? cool project thinking of maybe doing it with my camp
nvm i looked at the tutorial for the pcb and i get it now sweet project but the cost grows quite quick though
Yes, the cost grew. I was hoping to keep it under $5, but not counting the circuit board, there is about $8 in parts. <br/><br/>If you want to go cheap, use an Attiny11 and leave out everything but the button and CdS cell.<br/><br/>Tom Weber took simplicity to an art. Check out his instructable, which inspired mine:<br/><a href="https://www.instructables.com/id/Programmable-LED/">https://www.instructables.com/id/Programmable-LED/</a><br/>
Dude, awesome job!!! This is one of the coolest things that i have seen that have to do with led's! ;)
Very well done! This you make a great kit!
awesome instructable, it was well put togethen and it made me want to go and salvage materials for a whole army of them. Rating:5/5 Vote: +1
Great project, I really love it!! I love anything whit LEDs!<br/>I made an Instructables yesterday,<a rel="nofollow" href="https://www.instructables.com/id/LED-Snake/">LED Snake</a>, lots and lots of LED!!!<br/><br/>rate:***** <br/>
