Hi all, I have a feeling that I'm being incredibly dumb, but I am playing with multiplexing with one of these and I think I'm powering it wrong, but it's working :confused: I understand Multiplexing and I know that others have created programs and posted schematics and code for this display...

Hi all, I've been prototyping using through-hole components but now want to move to SMT - I can solder SMT components well enough, but I'm looking for a decent supplier of SMT resistor/capacitor kits in the UK at decent prices - CPC want £65 for a kit of resistors! I would prefer a kit over...

Hi all, I have a Sparkfun Serial LCD display and I have no problem writing to it at 9600baud from a Basic Stamp 2. I can also write to it at 2400 baud from the Stamp after changing the speed without any problems. However now I'm struggling to get a Picaxe 08M running at 4Mhz to send sensible...

Hi guys, I bought one of these 4 digit 7 segment displays a while back and now I have a use for it in a project - however I cannot figure out what the pinout is whatsoever? I haven't powered it up since I got it, partly because I don't want to burn it out by wiring it up incorrectly, and...

Hi all, I'm looking at purchasing this dust sensor to use in an environmental sensing robot. I know that using PULSOUT is the better choice in this instance but please bear with me: Looking at the datasheet, in order to trigger the sensor for a reading, you need to send a pulse cycle of 10ms...

Hi all, Just a quick mention of something I came across - Sparkfun's latest video ad features the PICAXE - further exposure in the US of this excellent microprocessor! Video available here.

Hi all, If anyone here uses Diptrace, please could you let me know where to find an LDR in the libraries? I've looked everywhere and can't find one, so I've resorted to using a variable resistor part but I'd like to do it properly. Many Thanks, Morrolan

Hi all, I'm trying to hook up a Parallax Ping Ultrasonic sensor to a Picaxe 08M. So far I have the sensor returning the raw distance every second, and I have divided it by 2 to remove the return trip from the echo, but I was wondering how best to allow for the compensation value to convert the...

This should probably be addressed directly to rev-ed, but is anyone aware of any plans to introduce the simulator to either the linux or mac versions of AXEpad? My main OS is OS X 10.6, but I find that I use the simulator a lot so in order to do that I'm having to run Windows 7 in a VMWare...

Hi All, I'm currently trying to convert some BASIC Stamp2 example code from Parallax' PING sensor to work with a PICAXE, but I've hit a couple of translation issues. Please could someone explain the difference between the following 3 forms of multiplication taken from the PICAXE manual? *...
