PICAXE, Load Cell and Tachometer Project

[hartparr]

I am new tp PICAXE...but it looks right up my alley for a project I've been brainstorming on.

I want to be able to accomplish the following in my project.

1. Show real time readings from my Load Cell on an LCD screen.
2. Show real time readings from my Tachometer on an LCD screen.
3. Take the readings from the load cell and tach at the same exact time. Multiply them, then divide by 1000 every couple of seconds and display the result on a 3rd LCD screen.

First, can a PICAXE do this?

Second, how would I go about figuring out what load cells and tachometers are compatible with PICAXE....and even if it can interface with these inputs?

Thanks Folks.

Welcome to the forum.

Your questions are a bit "chicken before egg" in so much as we can only say if a PICAXE can do it if you provide spec of the devices you want to use but then you ask which devices to use!

The PICAXE uses its power rail as reference and the ADC inputs give a reading as a function of that voltage.
So, a PICAXE on a 5v supply will need a sensor which puts out a signal in the range 0v to 5v.

Load cells are typically much lower voltage and so would need amplification.
The tacho should be fine but they can be analogue or digital. Totally different methods for reading.
The LCD part is easy. Suggest a simple serial one such as the AXE033.
