Luke, I do have ACS712 modules for 5A and 20A. I was thinking that +5A @ 12V might be sufficient, but I'll use the 20A module first. The circuit I am working on will use the MOSFET (NPN) to switch the ground on/off to the coil (top button on side of coil). The ACS712 will measure current on the +12v...

Luke & Matt et al, I am taking a different approach. I am using the Arduino Nano to capture the samples and then send the captured data to a PC application that will chart the values. I am planning on releasing the code on GitHub. The app appears to be working, although currently is measuring 0A cur...

Matt & Luke, Many thanks for all of the work you have put into this project. I noticed 2 issues with the code that was posted on Apr 19. Item 1: capturing more samples than what was intended 292: while (micros() < time_now + interval) 293: { 294: for (byte i = 0; i < numReadings; i++) // test only f...
