For the diagram, I used part of one of Bob's drawings, and added the Arduino components. These are the components I used: - Funduino ATMEGA328P Development Board - ACS712 Current Sensor Module 20A - SLA-12VDC-SL-C 12V 30A relay module I had never worked with Arduino before, so I just bought what I thought made sense. The Funduino board might be over-kill for this application; I'm sure there are plenty of alternatives available. The Funduino board is apparently an Arduino-compatible clone. All of the components were purchased on eBay. For expedience, I put the current sensor between the prop adjuster switch and ground. It would probably be better to have the sensor between the switch and the prop, on one of the power lines. That would allow the code to see positive and negative readings, depending on which direction the pitch is changing. You could then prevent further movement of the prop in the same direction after a limit has been reached. Right now, the code cannot determine in which direction the blades are moving. The txt file is the Arduino code. Replace .txt with .ino to open it in the Arduino code editor. -------- Doug Read this topic online here: http://forums.matronics.com/viewtopic.php?p=470727#470727 Attachments: http://forums.matronics.com//files/ivoprop_control_186.txt http://forums.matronics.com//files/arduino_prop_control_998.jpg ________________________________ Message 2 _____________________________________ Time: 09:17:13 AM PST US Subject: AeroElectric-List: Re: IVO Prop current limiter From: "kfav8r" > This might be another opportunity for an open source > project.

Bob, I'm open to any of your great ideas. I had not considered a solid-state switch instead of a relay, but that does sound like a good way to go. It would be nice to have this in a small package. Right now, I have the Arduino (clone) board in an enclosure, and the other components in the separate enclosure I had been using for your original circuit.

In my mind that makes them a no brainer to incorporate when building multiple copies of something, instead of starting from scratch. http://www.ebay.ca/itm/Pro-Mini-Enhancement-ATMEGA328P-5V-16MHz-Compatible-to-Arduino-PRO-mini-/191679508570?hash=item2ca0fd305a:g:AxIAAOSwT6pV5YIu Boards like the funduino (uno clones) are much larger but include the 5 volt power supply regulator and USB interface and are usually more convenient for one off projects or a first project.
