Let's Make Robots!

Picaxe 28 circiut board robot

I am trying to make the robot in the start here section.  The motors work when I hold the wires to batteries but when I try to attach them to the board they don't work.  I have followed the instructions carefully and soldered the wires to the pins (as I don't have connecters).  I have tried several times and am still stuck.  This robot is for a school project and has to be ready in two days.  I really don't know what to do can anyone help?

Can you take a picture of your board and attach it here? And give us a bit more information on your setup.

Indeed. Please make sure your pictures are well lit and in focus, and that your description of your set up is very clear.

We can help best if you give us good info.

Thanks, I've uploaded the photos in another comment (me being a numpty didn't twig to reply to the comment!)

They're the best I can get them in focus with you still being able to see whats going on.


Ok, It's the robot in the Start here section. The two wires from one motor go to A and the two from the other motor go to B, thought at first it was my solder, so i re-soldered but that didnt work. It works when the wires are just held to the battery thing but not when they've been soldered to the pins and into the board.

The pictures aren't very good as it just goes blurry

A good, clear picture of your board and the soldering job as seen from the top and bottom of the board would be really helpful.

  • For example, a common mistake is to have one or more of the chips inserted in the board backwards. But your picture is too blurry to see if this is the case.
  • Another common mistake is poor soldering contacts, or solder bridges connecting something you don't want connected. Again, we can't quite see that from your pictures.
  • So please take the time to get some good pics posted. Honestly, it will help a lot.

Also, please provide some detail about your set up, and what you have done so far.

  • What batteries are you using to power the board (how many and what type)? Are the batteries new or freshly charged?
  • Did your program load properly from the Picaxe Editor?
  • Post your code as an attached file. The problem could be hardware or software at this point.
  • Are you able to get the board to do anything? Flash an LED, etc?


Erm im using 3 new non-rechargeable batteries, and I havent managed to get it to the programming stage yet.

The board works with an LED.

We're trying to work on the photos, but i cant get them zoomed in close enough without loosing focus and them going blurry. I've checked the chips against the instructions to make sure they're right and they look the right way round.

I've also checked the solder and there arent any solder bridges

this is a little confusing:

I havent managed to get it to the programming stage yet.

So, did you upload any program at all to your 28x1?

What I do for clear pictures is get as close as possible that the camera will focus on. Even if it is zoomed way out and the thing you want to display is only a small part of the picture, this is OK.

Then, take your picture in a image editor (there are many free ones online) and crop the picture down to include just what you want to show. Most digital cameras today have plenty of resolution, so cropping down will still provide you will a nice clear picture that we can see detail on.

And do you have a multimeter available?



Thanks for all your help.  Here are some better pictures.  Sounds like a stupid question but someone just asked me if I have to program it before the motors will work.  I haven't programed it yet.
