I have posted two bits of code below, they both pause for 10,000ms but the do...loop option is 1 byte smaller. Is there any advantage to using for..next over do...loop other than it is a little less to type? for b0 = 0 to 100 pause 10 next do inc b0 pause 10 loop until b0 = 100 EDIT...

This is a really quick question but I can't seem to find an answer. How far can I realistically send serial data from a PICAXE without the need for additional hardware? I know it will depend on many things but I just need a ball park figure.

Hi, I need to measure a voltage between 0V and 0.05V (or even less if possible). I have a 12 bit ADC that I plan to use if the final project although I'll use the PICAXE's own 10 bit until I get it working, I could resort to 8bit if it isn't possible to amplify with enough precision. Is it...

I'm about to upgrade to the release candidate of Windows 7 and I was wondering if anyone knew if the USB010 driver and Programming Editor itself work correctly? I'll be doing a Dual (well technically Quad :eek:) Boot so its not important if they don't. If no one knows I'll install them both and...

Hi, I've been given an oscilloscope but I can't seem to get it to work correctly, I have no experience what so ever with scopes so it's probably just me (I hope atleast). I've attached two pictures, one is of the scope in general and the other is a trace of a 12V AC (50Hz) signal (apologies for...

I've got a reasonable collection of IC's and other electronic bits but I've got no idea what to make. I want to build a challenging project that will prove educational. I'm happy to spend as long as needed on it. I'm doing GCSE electronics (I haven't yet done the final exam however I got almost...

I have a couple of XBees on order from tech supplies however I forgot to order some PCB sockets for them:o. I am yet to make an order to rapid and I have a local maplins however I can only find 2.54mm pitch sockets. Does anyone know if the 2.54mm sockets are suitable, else where 2mm can be...

For my GCSE project I have made an shed alarm, however it is quite power hungry as a result I want to have both batteries and a transformer to supply it. Its almost done I just need to add the power supply. Would the attached circuit be fine, or would I need to add diodes or other components to...

I'm not sure if this is at all possible but could a PICAXE (08M in this instance) be programmed to give multiple PWM routines off any output through programming. If it was changed to run at 8Mhz then pulse the outputs from the code at different speeds to get a number of fading outputs. This...

Hi all, I've got a few questions relating to two PICAXE projects I currently have. The first is monitoring a 7.2V battery (six 1.2V cells) on an electric remote control car and when it drops below a specific voltage (as yet to be decided) it will switch one relay off and turn the another on...

I am looking to by some 0 ohm resistors to act as link wires on my PCB however I can't find any at maplins so I have found some 1 ohm resistors however it says "Min Res 1R". What is meant by this and will they be suitable for what I need (1 ohm should be negligible shouldn't it)...

Whenever I try to test this code it always skips waiting for a digit to be pressed on the keypad and "makes on up" it seems to change what digit it uses as well (I've used to debug command). Any idea's why? Here is all the code I've currently written(not finished yet but the password entry is...

Firstly I apologise for this question I imagine its simple once you know how. I have a 6V battery that will power my 08M (just testing my LCD display for now, will later be upgraded to a 28X1). How can I find the resistance the PICAXE chip to work out what resister I will require? Or am I...

I've just deigned this board (see attachments), I was wondering if anyone could see any mistakes? I am yet to add additional Inputs and Outputs to the PICAXE chip so I'm only really concerned about the LCD Firmware and the download circuit. Im using this LCD Firmware Chip...

I am trying to program an alarm using 28X1 chip for my GCSE Electronics coursework. I am going to try and use a reprogrammable 4 digit code and a keypad. I've already made the code below but haven't made a prototype yet (I'm still awaiting delivery of the chip ect.), so I'm uncertain if the code...
