Hi,
I've had a go at doing a circuit (albeit badly).
Attached is the circuit...the main component is the pressure sensor which outputs between 85mV and 145mV. I connected this to an amplifier to increase the voltage to between 0V and 5V (think I am missing a few connections). The output then goes to a LED controller chip which then lights the LED's (bar mode) from left to right depending on the range of pressure.
I also placed a A/D convertor on there as well as I want to sample the voltage and then send it to a computer, eventually, as well.
Any advice recommendations welcome! Its been sooo long since I wired something up I feel embarassed posting the diagram!
Cheers,
Craig
