i am expected to use sort of an analog mux circuit to switch between the two. any idea how i can do that with a 4051 mux? i don't know much about how to set the time intervals when the mux circuit reads between the two.
Hello! i am using the mbed LPC1768 microcontroller and i need to data log some calculated values from the program as well as data entering the analog input and leaving the output pins. i have tried interfacing with matlab but the program i got from the net only outputs 0-1 peaks while my sensor...
hello! has anyone ever done anything related to pitch control of wind turbines or similar? or does anyone has a good reference site for the programming part of this application? i am writing my program in this view but will appreciate a guide list of algorithms. Thanks!!
Hello! i currently have an lcd display powertip 1602F B which i want to used for my project. however, all inputs on my mbed have been used up and i need advice for selecting the most user friendly microcontroller which i can use for the display. any schematic circuit and codes will be most...
hi. a quick feedback about what i did. before implementing the above i tried the circuit with a full wheatstone bridge. i am using the output of the amplifier as a control parameter to actuate a servo motor via some programming with mbed controller. i supplied the amplifier with +12V and -12V...
Thank you very much! i will try to do that in lab on Monday and come back with some answers to your questions. as for the resistors i have used all 1% as recommended.
Hi..i am indeed using the RS 846-171 24 pin DIL amplifier and i am using all the recommended components in the datasheet. yes i have myself built a half wheatstone bridge which i am using for testing purposes for bending strain. how do i know the range of R3 and R4 i will require? I have...
Thanks for the reply. I indeed forgot to include the values. the IC is the strain gauge amplifier and the circuit around is for reducing noise, drift etc and also to adjust the bridge initially to zero for bridge imbalance but the latter function is not working (or maybe i am not able to do it)...
