I am new here and I have bought a mega2560. The scenario is: I am providing voltages to some display. First I need to find the differential of the voltages with respect to time and continuously having a check on the value of dV/dt if it is near to zero. If it is near to zero then I stop supplying the voltages. Can some body provide me guidance how I can implement the dV/dt or any link highly appreciated.
thanks for reading the problem
