My first post here !

I bought a made in China esr meter (MESR100) recently. It's crappy and its auto range doesn't work.
So, I am thinking of assembling one by myself. The esr meter schematic is readily available on the net but not the firmware. I am thinking whether if it's possible for me to arduino AVR microcontroller to drive the circuit.

Any comment from the expert here is much appreciated.
Thank you.

 

I have decided to give a try. IF I manage to get the coding to work, can I hard wired the ATMega328 chip onto the esr meter board ?
