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 :)

Microcontroller help!

So I'm working on a project to build a binary clock style watch, though I have very limited experience and knowledge about circuitry and microcontrollers. As of right now I have found a relatively simple project on this site I wish to replicate and downsize to fit in the size of a watch. The design of the circuit is based off the layout in this project:https://www.instructables.com/id/Simple-Binary-Clo...Now I have read up on microcontrollers and microprocessors. I also read some stuff about oscillators and how they can work to essentially synchronize the internal clocks of microcontrollers making them more accurate for clock uses. First is this true that a crystal oscillator can improve the accuracy of a microcontroller? And if so, how could I add a 16.000 Mhz crystal oscillator to the circuit presented above? (I want to use a 16.000 Mhz oscillator because the code written for the microcontroller is based on the 16 Mhz internal clock, so this should line up fine)Thanks if you can answer these questions!

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

Electronics Project Ideas which do not use Microcontrollers

In the past I have used various dev boards(Arduino,RasPi,Intel Edison, Particle Photon,etc) for projects. I am planning to make a couple of projects which DO NOT require the use of a Microcontroller. For some reason  I have this mental blockade of innovative ideas which I can implement without using a Microcontroller. If you have any cool non-microcontroller based project ideas, share them in the comments below & I'll try to make an Instructable out of them.

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.

how to connect a 6 lead RGB LED to a basic stamp2, or an Arduino?

I'm just learning about Microcontrollers, I've purchased 6 different books with all kinds of projects in them, unfortunately none of them speak of a 6 lead led.

Impossible to identify microcontroller? Answered

So I took apart a remote control for a cheap helicopter. There is a 14 pin microcontroller on board. Unfortunately it looks like any other 14 pin IC out there and there are no markings on it. 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?
