Hi, I just received one of these breakout boards from Sparkfun and hope to power my picaxe projects from my blackberry charger: https://www.sparkfun.com/products/9614 I could have sworn a little while ago that I found a thread here that covers using these, but now I can't seem to find it...

Hi, Is it possible to use a simple voltage divider to get 4.8v from a 12v supply, rather than using a 7805? I have attached a simple circuit diagram without capacitors for clarity. Many thanks, DDJ

Hi, I have an AXE049 board that I programmed to communicate with my AXE133Y OLED module. I now want to be able to read the value from an A1302 linear hall effect sensor using the AXE049 but can't figure out how to connect the sensor to the board. Can anyone help? Thanks, DDJ :confused:

Hi, Not sure where to post this so starting out here. I have been reading the forum on a tablet computer browser (not the App which requires a separate thread) for the last few weeks and have noticed that some of the buttons are a bit small for easy use with fingers as opposed to a mouse...

Hi, Does anyone know a low price UK (preferably) supplier for UGN3503 or similar Ratiometric Hall Effect Sensors? I need 8. I've tried Farnell and Rapid as well as ebay with no success. Many thanks, DDJ

Hi, I'm drawing up plans for an LED cube. I'm going to start at 3*3*3 single colour and progress from there. My aim is to reach 8*8*8 with RGB LEDs. I'm going to multiplex the LEDs and need to expand the Picaxe output ports through the use of one or more shift drivers (depending ultimately on...

Well, my daughter's water spraying alarm clock got nowhere - not helped by me fritzing the pump the day before the competition! My next project will be an LED cube. I'll be starting small - 3*3*3 single colour to get my eye in, but ultimately I'd like to do a 7*7*7 (or maybe 9*9*9) RGB like...

Hi, I have an AXE049 board and the Picaxe shop link here says it has: "Solder pads to allow a piezo and servo/serial LCD to be added". In the attached diagram (ripped from the AXE049 pdf - sorry!) I think I need to connect my AXE133Y to the solder points in the circled area (0v, Out7, V+)...

Hi all, Back after an absence of a few months. I'm still building my alarm clock which sprays water, but time is now critical so all help appreciated. The first competition is less than 2 weeks away - would be awesome if the Picaxe could take centre stage! I have an AXE133Y display which...

Did anyone manage to order one yesterday? I hadn't realised it was the launch date so I missed it :( However I have registered for one and hope to get it soon - then the interfacing can begin!

I have an AXE133 LCD display (which isn;t working but I will follow the hints here to see if I can make it go) . I do however have another question that hopefully someone can help me with: I want to connect my lcd to a DS1307 clock (I didn't buy the AXE LCD with attached clock) and was...

If I don't have a backup battery right now, do I need to connect the Vbat pin to somewhere - and if so, where to? Ground I guess?

Hi, If you follow this thread I have concluded that I fried my first 08M2 chip. Should I chuck the old chip, or is there something I can use it for? Perhaps I could program it as a normal PIC chip, rather than a picaxe. Any advice gratefull received. DDJ

Beginner's Blog ========= I'm new (very new) to PicAxe and having had a lay off of more than 20 years from electronics, am pretty much new to that too! (NB Some of you may notice some inconsistencies in my time line, but in my defence, one of my daughters is also posting here with this account...

While surfing ebay for cheap kit I came across these colour changing shower heads - has anyone seen these or made one? I'm curious how the water pressure powers the circuit? Item description includes:

Hi All, I have been reading the forums for a while, and asking for help for issues, but my specific aim is to build a digital alarm clock which - if you don't hit the off button quickly enough - sprays water at you. This is a school engineering project - it doesn't count towards my exams, just...

Hi, Daft question time. I want to set up a circuit using a 12V 1A wall wart through an L7805 circuit to provide 5v for my picaxe circuits. I have attached a circuit diagram from the 7805 data sheet that shows 2 caps, but when looking for the caps the only 0.33uF (330nF I think) I can find are...

I'm interested in getting one of these and programming for it. I've had a search in the forum but can't find anything. Has anyone used anything like this and can offer some advice? Should I buy common cathode or common anode? Probably doesn't make a lot of difference in the final analysis I...

I now have an AXE049 (http://www.picaxe.com/Hardware/Teaching-Systems/PICAXE-Tutorial-Board/) which comes with various peripherals and there is also a pdf tutorial (http://www.picaxe.com/docs/axe049.pdf) that I have been working through. This program - to flash the decimal point on the LED...

Hi, I didn’t think I would be back this quickly! :o Many thanks to everyone who helped before, I was successful in programming the chip to do the simple LED flashing program. Based on advice / comments / photos from my previous help request I re-built my programming circuit (breadboard) to...
