how do i setup(calibrate) the normal ACS723 board (not the low currrent version). The hookup guide on sparkfun is for the low current board. Any help? Any calibration or program helps.
The ACS723 is basically the improved version of the ACS712 (assuming you have the bi-directional version).
Google something like "Arduino ACS712" (5Amp).
What are you measuring.
A sketch for DC current is very different from a sketch for AC.
Note that these sensors shouldn't be used for 230volt AC.
