This is a circuit i have been workin on,,, Its a strain guage (SG 120 ohms)in a wheatstone bridge,op amp as a differential amp then the voltage is fed into micro and transmitted as a value ,I have been workin on this for some time now, It works but the voltage is unstable ,So when the strain guage is tensioned to give a reading of 3 volts it rises and falls by .4 of a volt,, this then give false reading in the micro
Iam stuck and have tried capacitors and different resistors
Any help would be much appreciated
cheers
