I'm totally new to Arduino, I'm working through the tutorials and whatnot, but before I go out and start buying stuff, I'd like to know if my project is practical for an Arduino.
What I would like to do, is switch fuel injectors on and off, mimicking their run cycle. In the car application, they are actually powered constant hot, and the ECU pulses the ground to cause them to fire.
So my goal is, push a button, injectors run at 50hz, or a 20ms duty cycle, for 20 seconds, and stop. That's it.
I had this working with a pulse generator, a timer, and a relay. But I couldn't get the relay to cycle fast enough, and then the pulse generator burned out, likely because it couldn't take the load.
So any tips, or critiques, I'd really appreciate.
