    Not understanding C, DC, & Z flags from my homework?

    I have a homework assignment i cant begin because i simply don't know how to approach it. I will post 1 question in hopes that someone will either help me solve it, provide information, outside sources or anything really. 1) Find the value of the C, DC, and Z flags after the execution of the...

    Confused what voltage would be depending on its location?

    I want to know if a simple circuit will have its voltage in take even if it becomes and open circuit rather than remaining a closed circuit. I tried working a simple circuit using the components and tools circuitlabs have but i personally do not have any clue on how to use their software. I...

    Cant understand capacitors capabilities?

    Cant understand the usage of a capacitors? I know what capacitors are but how do i know when i should use it. I read that capacitors act as a way to maintain voltage from sagging. Sagging in the sense that there is a voltage drop. But apart from that, were exactly do i know were it should be...

    Charlieplexing using the Arduino Uno?

    Hello everyone, I was given a project by my work (intership), the project consisted of me creating an Array of LEDs that portrayed a title (in this case, school Title), that will blink in a sequence at a very fast pace. So my school name is pretty long (21 characters), so i design or actually...

    How does the current flow?

    So i know this is basic, but i'm in my 5th quarter of Electrical Engineering, and i havent really grasp the ideal way the current flows. I have teachers telling that current flow from the (+) side of a battery or even the (-) side of the battery. But i was reading that, Electrons flow in the...

    What is the actual purpose of a Capacitor?

    I can't seem to understand capacitors in our everyday use! I understand that capacitors hold a charge, however, what is the purpose of that charge? Does it give of an Amp drop much like the resistors do for the voltage drop? Also, if I'm building a circuit, how many capacitors and which...

    How to choose a micro controller?

    I was curious, when looking at a list of AVR and PIC micro controller, how do we go about choosing the right one for our projects? What about size? RAM? What are the benefits of choosing a 16 pin 8 bit AVR over a 20 Pin 8 bit? How beneficial is an 8 bit over a 16 bit besides the more allowance...

    What size resistor to choose?

    Its very basic question i know, however, i was curious as to what size resistor would we need for specific schematic. I'm not sure how to test whether i need a resitor around 100 Ohms or 1M Ohms. How do i test what resistor i need? I know i need to know the voltage that will be running thru the...
