So this is for the cases when I know I need to have a power supply built into my project to run all of the components attached to the Arduino board, but I guess in general it might apply the same to Electronics in general I am not sure.
So I will start with an example if I have a finished product that's using a bunch of LEDs any electronic speed control or two various sensors like light or obstacle and then finally some Motors and servos.
So I'm not even going to pretend I know how to do this without following a step-by-step instructions but if I had something using a ton of Parts like this assembled and working.
The question would be, if I say detached a motor and just taped off the exposed wire leads so they wouldn't touch anything does the board still think the motor is there in terms of pulling in the power required and then not having anywhere to send it?
Similarly this could be the same kind of cause effect scenario if I was following a tutorial and decided to not include lights or some other component that needs power in which not including it wouldn't make the object not work or you just not have that feature, if I wanted to also consider that type of factor would I have anything to worry about in the same manner as the first scenario?
I just got my Arduino starter kit , and a 37 sensor bundle as well as a few other assorted components.
I thought I would ask these couple of specific questions first before I start just plug in stuff and unplugging stuff to see what happens.
Absolutely not.
Two fundamental principles are that current flows in wires, in continuous circuits, and devices or components draw the current they require from the power source.
When you are putting together a collection of modules, it is absolutely necessary to understand the power draw of all the components and provide a power supply that can handle more than the total current, while providing the correct voltage.
One thing that beginners usually miss is that motors and servos draw very large currents while starting up (typically 5 to 10 times the "free running current") and that also has to be taken into account. Always look for a stall current specification on the motor product page or data sheet.
It's kind of on point for the question I started this topic on but to expand on it instead of starting a new thread I'll add the situation here, so I know the input voltage for an Uno is up to 12 volts but it only provides 5 volts power to any component, without having replies going into X model board or Y model board does more or less is not the kind of answer I'm seeking basically can the Arduino Supply more than 5 volts if it's not directly sending the power as in is there a part that is designed for Arduino that can supply larger amounts of power that the main Arduino board only has to send data to.
Basically I just found out yesterday that even a DC motor that has enough torque for what I want to do needs probably at least 9 volts but if I wanted to get into brushless it takes a significant amount of more amperage sent into it. So Ken and Arduino run a brushless motor or two by using some kind of a power amplifier.
Basically I bought the frame and suspension of a 1 to 12th scale monster truck and I was hoping to use Arduino as the electronics on a baby step set up for learning before I went and spent stupid amounts of money on high and parts other than maybe the motors so it actually has enough torque to make the vehicle move under its own weight
The power from a system can never be greater than the power put in.
But this comes up a lot, a desire to unify power sources and then seeking to find ways to come up with diverse sources vs. ways to get diverse sources to 'co-exist'.
Well ya i more meant like having a box supply power like a pc, where it would say take 30v from battery or wall plug directly plugged into it and supply that power back out, and then use ardunio to just order the amount of power it should send as a data chanel not power, only power uno would pull is what it would need to run itself tyoe of idea?
This not possible?
