Hi all, I need to measure the pressure applied by someone's foot to a plate - what is the best sensor to acheive this? Is it true that piezo sounders can be used as transducers, if it is, would they be suitable for this application? (more detail! The sensor is measuring the amount of force...

OK, be patient with me here as I'm sure there is a simple explanation! I have a seperate pre-made circuit (a toy voice recorder module) which is triggered by a push to make switch. I want to activate this circuit via infrared. So far I have created the IR input stage using an 08M, the circuit...

Hi, I'm relatively new to picaxe and I'm playing around with having a small experimenter board with a download circuit, yes I know that there are probably better, cheaper pre-fab picaxe boards but I've got a bee in my bonnet about this now! All inputs/outputs work when I load a program to the...

I'm new to picaxe and I'm just having a play around on a breadboard to get the hang of things but I have a question to which I am sure there is a very obvious answer! I would like to know how to monitor an input continually - so I have attempted to create a simple program that will do the...

I notice that on the rudolph infra red upgrade kit there aren't any serin 10/22k resistors. The circuit diagram can be seen on page 39 of the following file http://www.rev-ed.co.uk/docs/axe107.pdf Why is this? I thought that these were essential for proper operation? Does this mean that if I...
