Papabravo, what do you mean by 'unless it is not'.Everything is in parallel, unless it is not.
With respect to a power source, if it is connected to that power source it is in parallel.Papabravo, what do you mean by 'unless it is not'.
If a device is in Parallel it is attached to the parallel device by 2 points instead of one. And Welcome to AAC!
Always have a rough time getting my head around this all. So your saying that my motor shield, and two motors are all in parallel, my controller, magnetometer, HC-SR04, LED and servo are in parallel, but how do they connect up as the motor shield is connected to the controller?With respect to a power source, if it is connected to that power source it is in parallel.
Things that are not connected to that source are not in parallel with that source.
Seems pretty simple, what have you read? Do you have different information?
Maybe you should learn to crawl and walk before trying to run a marathon. Things which do not share a common power source can still talk to each other if they have a common ground, and the voltage drop along the common ground is not too large. Separate power supplies for control and motor power are common. Here you want to make sure that motor power ground and digital ground and analog ground are connected at a single point, so noise from one sources does not couple into the others.Always have a rough time getting my head around this all.

Not too experienced I know...Arduino does not have the ampacity to drive motors hence the motor control shield which should have a separate source of motor power and not powered from the Arduino 5V pin. Another common way to power motors with Arduino is a switching transistor with a separate and higher voltage supply. In that case, you also want to use an optic isolator in the circuit to protect the Arduino from the higher voltage supply for the motor. Lots of things to consider when using Arduino with motors.
When you say the motor off the 5V pin are you referring to the servo? I've read that the maximum current provided by the 5V controller pin is 1A which is enough for my servo.Arduino does not have the ampacity to drive motors hence the motor control shield which should have a separate source of motor power and not powered from the Arduino 5V pin.

What is in parallel? And NO, the battery supplies power to the Arduino which has a voltage regulator to supply both 3.3V and 5V to the respective power pins and to operate the Arduino. Still a 40mA max on each I/O pin. The 5V output pin is good for ~400 mA on USB, ~900 mA when using an external power adapter The 900 mA is for an adapter that provides ~7V. Subtract the I/O load from that total and you are left with, once again, ~200mA+ on the 5V power pin depending on the power supply capacity. And when using a fresh new 9V battery to power the Arduino it may originally supply near 1A but goes down fast if any real load on the Arduino. Which is why I typically run my Arduinos off of USB or a Wall Wart power supply and not batteries. The Arduino uses power for many things just to operate, with nothing even attached to it but the power supply. This is why some people simply use a single programmed chip such as the ATtiny without all the peripherals.if everything is in parallel, every component will get the same amount of voltage from the battery.
The first image is not of two devices in series. To be in series requires that what ever current flows in one of them must then flow in the other. In that instance, you are guaranteed that this cannot happen as the current must split with some of it going through one and the rest going through the other (and no part of it going through both). They may or may not be in parallel as we don't know what happens to the dangling wires at the bottom. To be in parallel requires that whatever voltage appears across one of them must be the same voltage that appears across the other. So if you connect the two wires together they will be in parallel (and you then just have the same situation as in the right-most image).
The overwhelming majority of things in a circuit are in their series nor parallel with anything else in the circuit -- series and parallel are simply the two simplest ways to connect two devices, but if we were restricted to only these two ways, electronics would be very limited in what it could do.Always have a rough time getting my head around this all.

I don't think anyone ever claimed it was.SOFTWARE IS NOT ENOUGH, nor will it ever be enough.
I was not talking about developing an interest, I was pointing out that even to play with a crystal radio one needs to understand the very fundamental concepts of series connections and parallel connections. That is totally different from understanding the inner workings of components.I don't think anyone ever claimed it was.
What's the harm in dabbling in electronics in any form before rigorously approaching it from the proper starting point?
Do you begrudge people who started playing with crystal radio kits? I guarantee most of them didn't do a proper study of the inner workings of every single component before they built it. They just put the parts together and marveled at what is capable of. Then, later they learned how to adapt it or build new things based on that knowledge.
What about people who work on their own cars? Most of them end up doing wiring work and learning some electronics knowledge along the way. They rarely start with a ground up, fundamentals only approach to electronics. They tend to think of whole modules and subsystems. In some cases they too develop an interest in electronics, dig deeper, and learn more.
What about RC hobbiests? I could go on and on...
There isn't just one acceptable way to develop an interest in electronics. There might be some ways which are better at establishing the basics early. If you know for sure that you want to be an EE, I'm sure that some teaching methods and tools are preferable to others. But, most people wandering through this site aren't firmly committing their lives to electronics - they just want to play around, try out whatever project it is that they have in mind, and maybe learn something from it. For some, that's as far as it will go. For others, it will spark an interest in deeper learning. If an Arduino is part of what sparks that interest, what's so bad about that?
So obvious, so true!If two things are in parallel they experience the same voltage.
If two things are in series they conduct the same current.
