I've been using processing.org to capture data from Arduinos. I haven't tried with an RPi yet, but the link here is dedicated to just that.
Processing is more geared for doing really fancy graphics, but its ability to capture data and put it to a file is great, and, of course, send data to the Arduino.
I am inexperienced in interprocess communication, but, apparently processing can put the data out to MQTT check this link
Let me know how that works out for you!
Thanks for the reply. I am not looking to use an LCD, although that may be the best solution. For now, I plan on creating a simple set of LEDs and buttons.
I have looked over the code, and was wondering which part of the code is retrieving the status of a sensor? What if I have multiple motion sensors, how would I retrieve each unique value?
@GertSanders it is so small indeed, soldering with my soldering iron would be a problem. Maybe a 'secret' connector for this device would help @Koresh, just mount it if you need it...
The choice of MOSFET can be tricky. Seems that irlz44n was discontinued so you may need to find one adapted to the voltage and current you want to handle.
In all the cases you need to get a logic MOSFET too, meaning that they are fully open usually around 1 to 3V.
Also I'm sort of confused as it seems to me that L7812CV is a Voltage regulator, not a MOSFET. So if you are actually using that in the MOSFET spot it will definitively not work.
Especially if you are handling high current or voltage I would recommend using one from a reputable source for your MOSFET, I recently switched from mouser / digikey / aliexpress to mostly use http://www.arrow.com as you get free regular shipping, event if you order a couple of components (no affiliation to them whatsoever).
