picaxe

Hello,

I have recently built a Robot highly inspired from the start here bot.

I want to connect a buzzer to it....

http://www.hobby2go.com/shopping/details/82700/1600/acessories/buzzer-27mm-continuous.html

Q1. Can buzzers produce different sounds just like speakers???

Q2. How to connect a buzzer to Picaxe 18-Pin Project Board???

ok you probably get hundreds of people asking this queastion but i cant program my picaxe 08m2

it says error hardware not found on com1 (com one is the only one it will let me select)

i have tried everything  (apart from reset for i see no way to reset a picaxe 08m2

i am using the axe027 usb cable please help

One place where the "going got rough" with regards to my (Argentine) Picaxe Developer Site is with a Picaxe serial download cable that IS NOT RS-232, but USB instead.

If I can only reach those with a serial port on their PCs, then this project will never prosper. USB is a MUST.

STARTED 5.7.2012

Okay, so here's my project, what i am designing.
It is a robot arm!
Some stats:

- 4 servos, not very big
- PICAXE 14M as brain
- SM-S3317S 2.0kg at 4.8V
- 4 Rechargeable 1.2V batteries
- Polymorph and lightweight woodsticks as materials 
- Maybe somekind of sensor and IR receiver
- Potentiometer to control

Pictures coming soon!

I am currently working on a project where I need to teach my robot to "see" using an ultrasound sensor. In particular it must find and collect drink cans on a playfield and return them to a specific location.

To make the programming easier I wanted to take the sensor output from the robot and display it on the computer as a chart. As I am a terrible programmer I did a quick google search and came up with Gobetwino.

Hi!

I have bought a "Start here V 2.0" robot kit, with a Picaxe-28x1 IC, and Picaxe-28 Project board. I want to get the robot to take voice commands, and be able to talk back, and have been looking at the EasyVR Module.

But reading the manual for the EasyVR I can't figure out how to program the module trough the Picaxe microcontroller. Is this at all posible?

The manual mentions ROBONOVA, Arduino and Parallax Basic Stamp and says that they have a "bridge" program, but doesn't mention Picaxe.

Hi

I sort of started this question on another page, but I thought I'd move it here so I'm not hijacking someone else's page.

2 questions here;

1: I'm looking to move from using picaxe to Arduino. Can anyone give me any pointers on where to start? (I know this question's probably been asked elsewhere on LMR)

Hi,

I'm new to robotics, and just bought my first "LMR start here" robot kit. I haven"t recived it yet, but I am all ready having great plans about how to modify it (as I guess all newbies do).

So I have searched around to see what is out there, and I see that there are a lot of modules (or shields as they seems to be called in the robotics world) that can be conected stright to the Arduino.

So my question is, having just bought a Picaxe-28 Project Board, with a Picaxe-28X1 Microprocessor; can the Arduino shield be used with the Picaxe-28 Project Board?

The M2 Picaxe series has multitasking (time slicing) to allow up to 4 tasks to run simultaneously which the manual says is to make monitoring switches and flashing LEDs etc, easier to program.  I was just wondering has anyone explored how far you can take the multiple tasks idea.  Has anyone, for example, tried controlling a servo, monitoring switches and varying PWM on a motor?

I've got a feeling that everything will get a bit glitchy, but perfectly happy to be proved wrong.

Ta Daa!

Thanks to the kind sponsorship of our friends at  we will be able to offer a robot building workshop at Maker Faire in New York this year!

 Details will follow, but Picaxe will supply the PICAXE-08 Motor Driver Board, along with some funding.

Hi

A friend of mine is using a picaxe 20m2 to drive a milford instrument 20x4 LCD with a serial backpack. However, when he turns it on, it just comes on with a screen filled with triangles. The LCD is connected to pin 0 .The code he's running is below. What is the problem?

PS: This is my first post, so sorry if it's in the wrong place.

code:

I'm trying to build a climbing robot with a Picaxe-28 project board, however according to my design, I need 8 servos. Do you think there would be a problem to plug so many of those? Is there a way to feed the servos from two different sources of energy? As far as I know, the board I'm using is capable to manage that amount of servos. What do you think?

I know nothing about this so maybe a little orientation about what should I read would be great! Thanks in advance.

I have again problems with my IR-sensors. 

I have two of these http://www.dfrobot.com/index.php?route=product/product&path=36_55&product_id=114 connected to input pin 6 and 7 on my 28x1 picaxe projectboard. And even when there's no program on the microcontroller the sensors think that there's something infront of them, but there isn't.

I'm having trouble trying to understand how to use HPWM to control both motors of my 2-wheeled robot.

Hello guys,

I'm asking for advice as I've failed at the first hurdle with my Start Here Robot. I thought I would first make an LED flash using the PICAXE chip but so far I cannot connect to the chip to upload the software!

I am using a PICAXE28X1 and an AXE020 project board as bought in the lovely Start Here bundle!

Anyone out there who knows how to make Matlab work with serial communications?

I'm in the early stages of writing a matlab program to do inverse kinematics for a leggy kinda robot, and I want to get it to send the numbers to a picaxe via rs232 - seems fairly straightforward?

My test program is behaving wierdly

*code*

Picaxe = serial('COM4');

set(Picaxe,'BaudRate', 9600, 'DataBits', 8, 'Parity', 'none','StopBits', 1, 'FlowControl', 'none'); 

fopen(Picaxe);

fprintf(Picaxe,'1234');

Picaxe.ValuesSent

B = fread(Picaxe)

I'm working on a new robot and i want to control it with a usb-keyboard,

How can i connect a usb to a Picaxe 28x1 projectboard?

And how can i program it?

Thanks,

   On my current project I am using the Picaxe 28x/40x project board and I don't know where to hook up servos on it.  I searched around on the internet a lot but couldn't find anything about where to hook them up.  Not even the board's manual said.  I don't know if I missed it or what but I can't believe that picaxe would just let you go find this out for yourself.  I even entered the code to center a servo and went around on the board and tried to find were it was.  I also remembered to put a 330 omh resistor on the signal line of the servo.  I
