Banana Pi not detecting I2C

My hardware being used is a Banana Pi and Picaxe 28X2.

Controlling powerful motors

Hello guys,


I want to control a powerful motor not like the ones used (servo motor) I need something of the ones which work on 110\220


I am not sure if it is possible using picaxe, if so is there any tutorial or has anyone done this before?


Obvioiusly it should be powered externally and controlled by picaxe


If this is not possible what can the strongest servomotor provide me? Can it for example to move the steering wheel of a car?



Starter Robot Question

Howdy! I've been working on my "Start here" robot. I've not yet got a distance sensor (I am instead using a light sensor to take two readings moments apart, generate random numbers from them, and then compare those two so as to travel at random.) I do have a servo, but I have been enjoying having it play sounds through a speaker. Now, that being said, I'd like to hook up the servo, but A.) don't have the 330r DIL chip, and B) don't want to take out the darlington. 

Using PiFace but still using I2C

I got a PiFace Display in the mail not too long ago, and just cracked it open.
I got it as a tester to write a review, because I wanted the LED display and the infrared on it.

A few questions google has not answered

Hello everyone,


This is my first time building a simple robot. I am going to follow the "Start here" bot instructions, but I ordered a few extras to add in. I ordered a few leds and am trying to find a small speaker to use.

My questions:

1. What speaker can I use that will be compatitible with the start here project? (picaxe 28)

2. How do I wire said speaker to the picaxe properly? (I want to just play simple beeps and boops to start off with)

Second iteration of 08Lunchbox project board

Few days ago I recieved a package from Fritzing Fab with 10 PCBs of the second iteration of my 08lunchbox project board.

It is now smaller: 50x50mm and interfacing pads are completely redesigned to allow more versatility and eliminate jumper wires for some components. Here is visual comparison:

V0.5 on the left VS V0.9 on the right.

Interfacing motors from RPi with PicAxe

I've successfully hooked up the my RPi to my Picaxe for interfacing through this link:

I can successfully return the variables from B1 to my RPi.
However, I'm new to Python and  basically want to get started by writting motor control.


hello guys ,this my

custom designed picaxe master project controller board, this has a max ability to control upto 16 servos, 16 general purpose inputs and outputs. the required channel can be switched on using the on board dip switch, this is a extra security feature, as in the picture the board has an led indicator indicating power on and standby condition. this also has an onboard programming port which is a regular picaxe feature.

Maxhirez' PICAXE board

9-29-2014: This update just adds the zip file containing the board in its current layout. Send the zip file to your favorite board house and get your own stack of boards. :) I still have a few that I am dispersing.

A week or so ago Max was trying to find a layout for a PICAXE 18 or 20 board with an L293/754410 motor driver. He was hoping for something similar to what sanc04 assembled.

Okay so, I did this

And then I wanted to add IR control so i did thishttp://www.picaxe.com/docs/axe040.pdf

Connecting Bluetooth to starter bot (PicAxe)

I'm new to the bot thing, and just built the starter bot.

Can someone please tell me if this item could be (relatively) easy to connect and use with board I have?

Please don't buy the last one, as if this can work, I need one! XD

Three 08M2s and a Pi?

Hello! I'm a complete Picaxe n00b, but I have read quite a bit online, so hopefully my ideas here are not entirely inane.

I have been playing around with a Raspberry Pi as the brain for a small two-wheeled differential drive robot. It's very simple, but it more or less works.

Picaxe 08m2 Hotness / Solved - Chip was dead.

I want to make a ring of light for my robot but when i try to program or just give power to the picaxe 08m2 chip it get's hot, really really hot.

- I just got the picaxe 08 proto board http://www.picaxe.com/Hardware/Project-Boards/PICAXE-08-Proto-Board/


So i did everything as on this guide


But it's not working, I think the code is wrong? Can you help me ^^

I use picaxe 28x1

Thank you <3

Juice Box Robot Plan, Needs review

***UPDATE MARCH 11: After reading the comments here I have made a couple of changes to my plans. I have replaced the PICAXE 18 with the PICAXE 28 and appropriate board. I have switched to 3 AAA cells as a power source and I have changed to servos to power the "arms". When I wrote the original post used the word "arms" as a placeholder, but while I always intended to have actuation it was never actually going to be a set of arms.

Picaxe as an I/O expander for Arduino

As I was thinking of new features for my robot, I realised how painfully short I was on pins! The Arduino Mini just doesn't have enough! I'm not thinking of upgrading to a Mega, seeing how pricey it is and also because it's pretty huge. That's when I though of I/O expanders. Unfortunately, most are designed to be shields for anything but the Arduino Mini, so, again, I didn't know what to do. That's when I thought of using a Picaxe for expanding! I'm thinking of using a PWM or an analog pin from the Arduino as an output to a Picaxe input pin.

PICAXE 28X1 and the PLAY command

I came across an interesting problem tonight and thought I would share it.

I was working on Ajax, (robot #1) and decided to use the PLAY command in PICAXE BASIC to make him "sing".

It looked really easy to use, preloaded tunes, give it the pin for the piezo speaker and the number of the tune and it should work.

And it did kind of work.  I worked on EVERY output pin but the one I had the piezo speaker connected to.

I had the piezo speaker on output pin 3 and got ...nothing....
