thanks ---

About the PIC, I am quite familiar with the 16F741 but I never used the Analog to Digital Converter capabilities of it... I guess this is an occasion for me to give it a try.
My other question is if for the voltage amplification section, can I just use regular 741 op-amps and get a decent output ? And does the sensitivity of the strain gauge depends on the manufacturer of would it depend on how I set the resolution of the PIC's ADC?
Thanks in advance...
