Arduino fuel injector tester.

I'm working on an Arduino powered fuel injector flow tester. I started out with a simple wave generator and a timer, but the relay I was using couldn't operate quickly enough, then I burned up the wave generator lol.

It seems quite a few people have started on different testers, and either never finished them, or post Youtube videos and won't post up the code. I guess that's their pejorative, but not really how I roll.

So, it's my personal first Arduino project, and I intend to keep it simple.

I bought a heavy duty MOSFET board capable of 100V and 100A here, https://www.tindie.com/products/DrAz...00a-up-to100v/

In theory, that should allow me to turn the Arduino's 5v PWM output into a 12v output, or whatever I want really. That will cover the dynamic testing. I'm simply going to run them at 50khz to simulate 6000 rpm, I see no need to run them through a range of RPM like I see some people doing.

Then I believe I should be able to write an even simpler program to short the injectors open for a set time, which will give me static testing and my actual flow numbers on my decaps.

So, next week as the parts get here and I teach myself IDE programming, stay tuned for more updates.
