Hello all, new here and have a feasibility question. My planned project is to change my tachometer and use as an ammeter for my electric vehicle conversion. My rough basic plan is to use a closed loop hall effect current sensor and an Arduino to change the voltage to the corresponding frequency to drive the tach needle which would show the actual current being drawn from the batteries during operation. I am working at logging the frequencies which drive the tach now, but thought I would check with those who have a higher pay grade than this newb with concerns to the feasibility and practicality of using an Arduino in this manner. 8)
Thanks in advance for any thoughts on this!
