Picaxe Roboshield

I think to design robot shield with Picaxe 14M.

It has 14M CPU,L293D motor driver,Memory circuit  24LC32, programming input,male headers and some else parts.

Do you think it can be good?

picaxe microcontrollers

hi just wondering can i use a picaxe microcontroller without a project board (ie on its own or a bradboard?)

i dont think i even want to do this but it would help me learn a bit about how stuff works, probably

Problems with programming picaxe

Hello! I have a problem with programming PICAXE 08M.

It says it can't connect to the CPU. And i don't know why it says so.

I'm doing everything what it says but it doesn't help me.

Can YOU help me to program it?

EDIT: I connect the cable to the COM port and put batteries. Then i wroted the program and try to move it to CPU.

tts 256 text to speech serial data

If anybody knows this it would be great help to me. on the tts 256 data sheet it says on start up that the tts256 transmits serial data to host processor, but Im not sure what data it is sending for me to receive. Im using a picaxe microcontroller.

Funny behaviour in a picaxe...

Hi all, I hope people can help with this, cos I'm baffled.

I've been using a picaxe 08M2 (the new one) to control a stepper motor, which works fine until I want to use the free input to trigger the motor.

When I do that no input affects what the chip is doing

I took it back to the program, nothing odd there, so I tried using a pushbutton switch to turn an LED on and off.

If I use this program:


if pinC.3 = 1 then

Problems with axe 08m and l293n


I have a teeny problem - I'm playing with stepper motors for my next robot, the plan is to have an 18M2 sending serial packets to a pair of 08M2s which each will control one stepper, to save outputs on the 18.

My problem is this, when I have the 18 running into the L293 driver the motor runs perfectly, but when I use an 08 nothing happens and it gets hot (I fear the magic smoke)...

Mapping With Picaxe

   For a current project I want to try mapping a room with a picaxe but do not know how to get started.    With this project I want to be able to find my way to certain places in the room and want to be able to know when I got there.  For example I would want to map a room and I would want to be able to set different spots in the room to look for objects.  Then once it found an object in a certain spot it would take it to another predetermend spot.  An example would be if it would find anything next to the foot of my bed pick it up

Check out the new picaxe.com website!!

Hi guys, have you seen the new picaxe.com?

I am proud to say that I was on the sideline when it was made :D

Let me know what you think, all comments are very welcome, I'll pass them on :)

miniq or start here?

hello everyone ive recently made some robots that i couldnt quite complete because of lack of experience so ive decided to take some good advice and look for a nice easy robot kit to teach me programming and other robotic skills and so i am stuck on 2 kits. i cant decide which to use.

Tamiya Twin motor gear box

Hi guys 

I have a question 

Does the tamiya twin motor work with the L293D Motor Driver IC

I am going to connect it to a picaxe would it work.

Lots of strange Sharp IR Noise…?

Hey everyone. So, I just finished my first robot in a few years, my first being 2 1/2 years ago. This one is a lot more complicated in terms of hardware since I made my own boards and all, and have 5 ICs in one circuit. I'm done with programming and everything runs well but there's one ongoing problem with my Sharp IR GP2D120 sensor.

The robot controller app is out! Woo Hoo! Finally, a Android-based hobbyist robot controller that works with every microprocessor. There is no corresponding … Read more

Accuracy of 28 X1 without external resonator?

In my circuit, I have 2 Picaxe 28X1s. The only suitable external ceramic resonator I have is on the 28 pin project board and I don't want to ruin it by accident during desoldering. I am making my own board for each Picaxe, and need to know how accurate the timing of the Picaxes will be only using the internal resonator. Picaxe A is using 2 PWM channels driving motors on a separate power supply handled by an L293D, all other outputs to drive other ICs, will read 1 ADC channel, 2 digital sensors, and 1 digital input.

Where to begin with PIC chips?

Okay, so I've gone out & bought my Arduino clone, had fun* with it, bought a truckload of ATMEGA 48-328's & had fun* with them and would like to now broaden my horizons a little. I'd like to see what's on the other side of the fence & give PIC chips a try. From what I can see, both have their advantages/disadvantages & can excel in some areas where the other may flounder.

Help with Hserin/Hserout commands?

I have 2 Picaxe 28x1's that will need to communicate serially with one another while each performing tasks such as PWM, reading ADC, simple outputs. As I understand, the Hserin and Hserout pins/commands allow the Picaxes to recieve serial data in the background, store it somewhere, and read the stored data whenever necessary. I need Picaxe A to do tasks, and then send 2 variables to Picaxe B without interupting B's program flow. B needs to be able to look up the variable sent from A whenever necessary and continue on. How would I connect the 2 Hserin/Hserout pairs on each Picaxe?

28X1 Pin 7 (Serial Out) Used as Normal Output??

Is it possible to use pin 7 of the Picaxe 28x1, which is normally used in the download circuit, alternately as a normal output that could in my case drive a single LED? If so, what would be the code for it?

Picaxe Serial Communication Through Prog. Socket??

Hey, I'm wondering: If I have 2 Picaxe 28X1's that both have their own programming sockets, after programming them, can I use a male to male audio cable and connect their sockets, and send information from one to the other with serout commands? One 28x1 sends info to the other, no data is sent back, so only on serial line is needed. Is it possible, and how would I implement it?

Continuously Rotating Servos

I have a pair of servos that were modded to rotate continuously about a year ago. I've been trying to make them rotate with the command:

servo 0, 1 : servo 1, 1

but I find that this does nothing but make the servos twitch. However, when I use:

servo 0, 1 : servo 1, 1

wait 2

the servos rotate clockwise for two seconds. Furthermore, when I use:

servo 0, 2 : servo 1, 2

Picaxe USB driver issue

I have just received my Picaxe 28X1 Starter Pack and, after an hour of trying, am still unable to install a driver for it. I am running Windows 7 Ultimate, 64 bit on an AMD Phenom II X6 1035T at 2.6 GHz (or so they say). I have tried the self-extracting, self identifying driver, I have tried the manual install. I am not getting anywhere... well, nowhere good. I have combed the rev-ed site. I assume that the driver was included on the CD I got with the starter. It seems likely that I am just missing something obvious.

Any advice will be appreciated. Thanks!  ~Allen
