Advice on microcontrollers

Hey everyone. Long-time member of the site, but just now starting to get into microcontrollers. Looking for some help on choosing a good, easy line of microcontrollers/programmer (easy to use without sacrificing too much function) which would be good for someone new to microcontrollers. Would the ATTiny line of microcontrollers be any good, or would pic be better? Oh, I'm also a university student so cost of the microcontroller/programmer is something I'd like to keep low (if possible). Thanks to anyone who might be able to help me. Either respond here or send me a private message ... Thanks again :)

PIC Microcontrollers

Hello. I'm just making my entrance into the world of microcontrollers. But as I self learning everything I have a few questions. I recently purchased 2 PICS (16F648A) and a programming board. The board works fine and I got it to connect to the computer and reconize the PIC. I guess my first question is, Is all hex code PIC specific? Meaning would I be able to use this code "http://www.voti.nl/blink/index_1.html#16F630" for my PIC? The models are very similar but not exact. If not, I would like to do the standard "Blink an LED" as my first project. How would I write my code for this PIC and what materials would I need? Thanks!

Programming a microcontroller?

Hi everyone I have got a MICROCHIP - PIC16F616 to play with, I am going to write a little program and load on it. http://onecall.farnell.com/microchip/pic16f616-i-p/8bit-flash-mcu-smd-16f616-dip14/dp/1332199?Ntt=1332199 However, I have a few questions before I do this. 1. How do I know whether language I should write? like C or Assembly? does it tell you in the datasheet (link above), because I don't seem to find it. 2. What kind of program do I need for loading the program into the chip? is it also an information I can find in the datasheet? or it is really some common sense between programmer. My supervisor doesn't offer much help... Extra question Here is the link of open programming, I am just curcious that if I build this programmer (I have one for my chip, but just wanna learn something), does it mean that I can use this to connect my microcontroller and my computer, so to load the program into the microcontroller? http://openprog.altervista.org/OP_eng.html Many thanks

sensors microcontrollers

Hiya guys is there anyone that can guide me to finding an instructable that deals with interaction in remote places using a micro-controller. For instance people in 2 different locations in the world, want to engage or enhance social bond or interaction by using a motion or proximity sensor and internet of things for instance triggering a sound or an led light that can be sensed in a remote location. So one location motion is detected and the other location this detection can also be seen, if that makes sense? For instance similar to this kind of project  http://goodnightlamp.com/ Could this be done? Thanks

Advice on microcontroller selection

Hello I am a newbie to the world of microcontrollers and would be really grateful for some advice about choosing one. Basically, I’m doing a final year university engineering project that requires an MCU to take a number of analogue inputs, do some processing, and spit out an analogue output that will drive a loudspeaker. My supervisor has recommended looking at the Philips LPC2148 and associated development kits (http://www.olimex.com/dev/lpc-h2148.html) because it is cheap and looks able to fulfil the following requirements: I/O – three analogue inputs (so 3 ADCs), 3 digital inputs (two servos and a bus for programming the controller), and one analogue output (requiring a DAC either built into the development board, or one I could connect on an add-on board) Speed – a program size of about 500 floating pt operations, processing samples at a rate of up to 400/second, hence of the order 200,000 floating pt operations per second. I think the LPC2148 uses fixed pt arithmetic so would need to perform the equivalent of this in fixed pt. Support – in place debugging support would be desirable; ability to be run on Windows; overall hardware and software cost of £100 or less. Does this chip and its development tools look up to the job? If not, would you recommend an alternative? Are there any other major criteria I’m neglecting in the process of selecting a MCU? Many thanks, Sam

Agilart project: the visual way of programming microcontrollers from your browser

Hi all, about an year ago we faced a problem with a microcontrollers and how difficult were for us to use them in a simple home solar system. That was the reason to start our project Agilart (www.agilart.com) with the idea to make a simple web based program designer, where we can visually program the microcontrollers.  Now we have the site (www.agilart.com), a short demo video of the idea (http://www.agilart.com/community-and-support/video-tutorials/agilart-getting-started), and a few blog posts where we have tried to give some more details about the project (http://www.agilart.com/blog). We also made microcontroller's part and open source project (http://www.agilart.com/blog/agilart-runtime-in-github). We have plans for open hardware project for microcontollers designed especially for Agilart and providing features on prices under Arduino with Ethernet shield. But why I'm telling you all this? Because we need your feedback and help. We would like to ask you to share what do you think about the approach we propose; what do you think about programming using block-diagrams; do you think you can use such approach yourself; do you need such tool or you prefer programming? This will help us test our hypothesis, to check whether what we think will be useful is actually useful or it is cool only in our heads. This will help us understand does it worth to go further or not. Our vision about Agilart is to provide an easy and intuitive way of working with microcontrollers even from people without technical background. We see it as open source/hardware projects combined with some paid services to cover R&D.; So, thank you for reading this and I will appreciate any feedback from you. Thanks in advance for your time.

Is there anyway to identify possibilities. For example if I mapped where each pin goes on the PCB. Luke pin one goes to the LED's, pin 2 goes to the joystick, etc. Is there any way to "read" the chip to figure out what it might be?

Is it ok to use two ground pins in arduino?

I'm utilizing two power sources... the one that comes from arduino (5V) and one 12V transformer to power my stepper motor. In the 5V pins I am powering up LCD display and my water level indicator. Now, I utilized two ground pins for the two voltages (5v arduino, 12V) . At first I only used one ground for the two voltages because they need to be in a common ground but voltages are jamming together (i think) because every time 12v is on , the lcd (which is connected to 5V) isn't functioning well. So, I decided to use another ground from the arduino and connect it to my 12V source so it could still have a reference point to my 5V supply. It worked , the LCD functions well but another problem has arised. The rectifier diodes in my 12V transformer gets really hot. What could be the problem? . Does it have anything to do with using two separate ground pins in my arduino?
