    Accelerometer circuit design

    Ok , great , i understand what you are saying . But , what cutoff frequency would be appropriate to use for such a system? Is it logical to say that since we want a bandwidth of 400Hz that the cutoff frequency of the LP would be 400Hz ? The use of the LP is to cutoff noise, so we assume that any...

    Accelerometer circuit design

    I am starting to get a better understanding of the circuit. Your sampling rate is 48kHz if i understand correctly , you chose that because it is about 100times more than the bandwidth ? Or am i completely wrong ? And your low pass filter is at 6kHz , that is something i dont understand why. You...

    Accelerometer circuit design

    Well Dana , you gave me a lot of "homework" to study on . Thank you very much for the effort , your answer is very detailed and i am very grateful. I am not familiar with PSoC creator , so i will need time to understand your answer. You get the analog signal in the ADC , then you get the...

    Accelerometer circuit design

    Thank you very much for your answers , i am really happy that i can find some assistance and i will try to clarify the best i can. The accelerometer will be designed from the start. Only the capacitors are available and their output The method is referred as differential capacitive sensing...

    Accelerometer circuit design

    Hello people , I dont know if my question is under the correct category but anyway I need to design a very basic accelerometer circuit . The point is to take the voltage measuerement that a capacitive accelerometer provides and after proccessing it to output it . The circuit will probably only...

    [Moved] how to programm an arduino

    Thank you for your answers.But the arduino official startet kit costs 100 $ on amazon ( https://www.amazon.com/Arduino-Starter-Official-170-page-Projects/dp/B009UKZV0A/ref=sr_1_14?ie=UTF8&qid=1403601536&sr=8-14&keywords=arduino+uno ) , thats quite expensive. So i am wondering if the other...

    [Moved] how to programm an arduino

    SO i dont know anything about ardiuno , dont own one , but i would like to start learning the programming language it uses.I only know the basics of electronics(resistors,capacitors etc. and how to make a simple circuit)i have never learned any programming before.How can i start?

    i need help with a simple home project

    Hello, fisrt of all this is my first post. I know it is going to sound like a dumb question i am really newbie and i made a solar usb phone charger. It consists of a solar panel (3v) that charges two 1.5 v nimh rechargable batteries that charge the phone.My problem is that when i plug my phone...
