I have always had this question, but I couldn't quite find anything that answered it. I was hoping someone could shed some light on the question... Thank you in advance.

Hello, I am working on making myself a digital clock (as a fun little project) and I want to have two buttons, one to increase a value (like the hour) and one to decrease, mainly because I am tired of the clocks where you have to button mash the 'increase' button to bring the hour back down. As such I want to construct an up-down counter that would increment on the rising edge of one input and decrement on the rising edge of another. I have one that increments on the rising edge of the clock if the extra input …

I was proposed a project that sounds like this. Consider a set of logical gates like AND, OR, XOR or NOT. Allow for building any logical circuit by connecting such gates. Provide input (0/1) to a number of gates and collect the results at the output of some of the gates. Be able to read the description of the circuit from a file. Has anyone done anything of this kind? What would you do, how would you start/shape this problem? I am looking for any help as much as possible, open to hints and solutions, anything is helpful. Trying to …

So i have write the following code (above) and now for the second part i am required to apply the Complex Number into finding the voltage across the Resistor in a series RLC circuit. The following tasks : Create an executable program Resonant Circuit, which allows you to output the voltage across the resistor. Output is through the main function. ![Capture](/attachments/small/4/Capture.JPG "align-left") The characteristic values ​​of the resistance R (10 Ω), the inductance L (10 mH) and the capacitance C (10 nF) to be created as a constant in the function. Create a function voltageOverResistor that calculates the complex AC …

Does anyone know a good way to force javascript to evaluate all operands in a boolean expression? In particular, what I am tring to do is essentially this: return isValid(a) && isValid(b) && isValid(c); while this technically does work, the function is responsible for highlighting invalid areas on the form for user attention. Since the `&&` operator short circuits, it will only ever highlight the first invalid expression, possibly requiring the user to go through several rounds of correcting input data. Any ideas?

During some recent project issues I found myself asking this very question: **Does MySQL short circuit WHERE clause statements?** After doing some research and finding that several other people and technical forums have posed this question, with several answers pertaining to be intelligent but that amount to *"i don't know"*, I decided to perform some experiments. Firstly, how to test whether a statement is being executed or not? Solution: make it throw an exception. I initially tried some select statements with parameters and division by zero, but MySQL apparently returns NULL instead of a divide-by-zero error. So I came up …

I am trying to use Java to detect signals from the serial port sent from an IR circuit. When the IR circuit detects an obstacle, it gives an output of 0 volts and otherwise the output is 5 volts. Can I read these voltage differences directly on the PC using Java. Do I need to have a PIC or some other micro controller integrated in the circuit?

Hi everyone! Just wanted to ask before i begin messing around. Is it possible for two processes to access the parallel port simultaneously? So that if i short circuit Input pins to output pins of the parallel port one process will provide input to another one? I am using Windows XP and C++. The first process is a commercial one which cannot be modified. In my experience with serial port it was impossible to interface it when another process had the access. Thanks in advance!

I am currently working on a C# project that contains UDP and TCP connections, and outputs to a serial port,... etc... So I was thinking ... How hard is it to take a C# program and convert it somehow to be embedded on a circuit board? ... i.e: replacing the laptop with a circuit board and components with the software running on it I know that it is more achievable with C ... but I am asking about C# specifically Thanks :)
