Analog input 1?

Hey guys.

I ordered and recieved most of my things and was building my first robot! (looks like crap, but hey, off with the looks)

Anyhow, i was going though the manual in the START HERE page. At one point it simply says to plug the singal wire to Analagod Input 1. Fine, i thought. BUT WHERE THE HELL IS IT???

 

Argh! I have a PICAXE 28X1 board,but I'll include a few pictures anyway.

 

Any help would be appreciated.

Also, the batterie pack i'm using contains 3xAA batteries and has an ON/OFF switch, is it okay to leave the batteries in while testing if I leave it OFF?

Thanks again.

 

(you can simply edit the picture with paint and circle the place where I have to connect the SINGAL wire, that would be appreciated!)

B for Analogue

Analogue pins are beautifully described here. Even has the picture you are hoping to get.

And then some, dummy.

Hmmmm, the last picture

Hmmmm, the last picture talks about inputs/outputs, but I still can’t seem to figure out what input is designated as ‘1’.

Unless that really doesn’t matter…?

picaxe manual1

picaxe manual1, appendix E, page 78 describes pins and legs on the 28x1

(and it tells you to count clockwise, starting at the serial jack)

Thank you. :smiley:

Hey! What about the battery

Hey!

What about the battery pack?

Okay, I checked, read and studied. Now, I know this might sound noobish, but that’s because I am. Entirely. So, I seem to have found where Analog Input 1 is, BUT, now for the question;

how am I supposed to put in the SIGNAL wire if it’s being taken up by the PICAXE 28x1 board?

…thanks.

connect to the "leg"
connect to the “leg”, not the actual “pin” on the chip

...except the input in the picture is adc 2. 1 is the one above it.

Alright, de-soldered my Red

Alright, de-soldered my Red and Black wire to put 'em there. (I know I didn’t have to, but felt like it!)

 

ANyhow, plugged and soldered everything, connected the USB cable, set it up/installed, set the ports. Yet still, I get the PICAXE error telling me nothing’s detected.

I read somwehere that the voltage mustbe between 4.5V and 5.0… I have 3xAA batteries hooked up, should that be enough?

 

Thanks.

de-soldered?

What red and black did you desolder? The lines in the picture represent the wires connected to the Sharp range finder. Did you disconnect your power supply?

3AA should work fine.

My power supply a 3xAA pack

My power supply a 3xAA pack that’s connected to the V/G plug on the microcontroller (I actually just soldered the black and red wires to a 9V-looking wire/plug).

Here’s a picture to clarify.

no power
i made that mistake before, too. the problem is your two nine-volt-plug-looking things. The positive and negative poles are reversed, so what you’re doing is running the power to ground, and vice versa. I would just cut those things out and solder the lines together instead.

Great!

Aaaah, thanks Calculon320!

I thought that might happen, but hoped it was just me being paranoid.

Your help is greatly appreciated.

Thanks again!

Ah damn. I disconnected the

Ah damn.

I disconnected the 9V-immitating plug and soldered the red and black wires to the microcontroller directly. (I used the V and G schematic that Fritsl put together to know where to put them… it seems it didn’t matter where I had to put them as long as it was a V for power and G for ground… right?)

Anyways, I’m still getting the error… anyone got any ideas.

 

Thanks!

I think I’ll follow Fritsl’s
I think I’ll follow Fritsl’s advice and actually PM him about this…

Hey hey hey! What if I

Hey hey hey!

 

What if I stripped wires on the 9V-looking plug and reversed them? That way I could easily connect the battery pack without soldering! (though I would have to unsolder anyways :P)

Yes… no?

18

wait
I get the impression that you connected the V and G from the battery pack to V and G pins on the board? In that case, I’m pretty sure it does matter which ones …

**Oooooh… Ill unsolder them**<br><p>Oooooh... Ill unsolder them and await LOLGeek`s picture to see how he set things up since we share the same board, motors, ect… And the same name!

 

Thanks Calculon!
