I'm building a circuit for my project. However I'm a bit insecure about whether it is correct. (I'm from software myself).
It is the following circuit:
A couple of side notes:
- there are 15 Solenoid assemblies (Solenoid, Mosfet, Diode) connected in parallel.
- there are 3 servos all connected to one 5V regulator.
Since I'm not that experienced with circuitry, and neither are the people who will use this project after me, I'd like to make this circuit almost impossible to break.
So my questions are:
- Did I use the right parts to use solenoids and servos?
- Am I missing any parts that could make it more unbreakable?
- I've added a capacitor, but how many Farads would I need?
- When testing, I noticed that the MOSFET doesn't transmit all current, and it also takes a while before it is really switched off. Why is this?
- The solenoid needs to press a button but it only has enough force when ~19V is applied. I find it inconvenient to use this 19V supply. Could this be done in a better (=safer) way?
Thanks in advance!
