A main challenge to learning Arduino programming is that there is no debugger that will show you what your hardware is actually doing. Learn how easy it is to connect an LCD to write "logging" statements.

You do NOT want to attach LEDs directly to the parallel port. There are projects out there that will tell you you can get away with it, but you risk blowing up the port if you're not careful and with some ports, it won't work at all.It's possible to do but I recommended against it. See this...

To realise such projects you need an embedded device (as already suggested by ppolymorphe). These usually came with an adapted Linux distribution (most devices use a Debian based one). So I would not care about a specific Linux distribution but select an embedded system that fits your needs...

Do GPIO ports (on raspberry pi) can be used for serial communication? or, how we can connect multiple devices for simultaneous communication on single RX and TX of raspberry pi?Edit: I have two devices, a GPS module and a GPRS/GSM module to connect, both uses RX and TX to communicate with...

HiMy study field is electronics, and I want to build some gadgets like android watches or wears and etc. I know some thing about Linux programming and c++ language, and want to know if there is a Linux distribution like android for these type of electronic devices, I do forget learning android...

Please see my comment to the question. You don't even need to go far: http://www.codeproject.com/search.aspx?q=control+parallel+port&doctypeid=1[^].As you can see, the first found item is even about controlling LED through a parallel port.The only possible problem is: many article you...

No. There are protocols - lots of 'em - but no particular device has to use it, unless it is actually connecting to a communications medium - such as a LAN, WiFi network, or the internet which requires a specific form of communication like Internet Protocol for example. Even then, the...

Is there any library for WPF (XAML code) that contains Shapes or Geometries of Electronic Components like Fuse, Transformer, Wire, Resister, Diode and etc What I have tried:
24 Sep 2020 by Dave Kreskowiak
Probably doesn't exist. You're best source for component outlines is probably going to be for PCB layout software like Eagle. That have large numbers of libraries of components that have outlines for the device itself as well as pad layout and...

Well, you've come to the wrong forum, and the wrong site entirely. This isn't a "for hire" site at all. This forum discusses technical questions on coding problems.

Um...Android is a Linux distro... :laugh:There are quite a lot of embedded Linux variants: Wiki[^] provides a starter list, but there are loads of possibilities. Google[^] may help you get started looking for something suitable for exact project requirements.

Hello there, I am looking for a tutor in Electronics and IoT. I'm a programmer already but I need some insights into Electronics and IoT. We can discuss compensation once I get to know and understand your experience in the field. I hope it's...

Theoretically speaking, yes, but you won't want to get into so much trouble — they are not designed for this purpose. It would be quite difficult to organize such communication. You will understand it if you understand what GPIO is:...

i have a little problem in my projectmy program was coded in .net 2012 and the idea was when i press a number its has a sound with it ,means number 1 have an error sound when i press it number 2 have and accept sound when i press it so far every think is ok now i want to control a parallel...

Hi. I am working for a broadcast company. And i realised that we are using many kind of devices such as satellite recievers (both home type and industrial type), signal decoders, regular switches and routers and many more which even i dont know what they do. long story short, i wonder is there a...
