What else do you want to learn about Arduino?

We've been posting official Arduino Tutorials and members projects for years now and Arduino is one of our top 3 most followed spaces on element14 with its new products, videos, projects and discussions.

 

EXCLUSIVE Resources include:

 

published 3 guides to help you get to know Arduino:

 

  1. Getting to Know Arduino : Part 1 : Hello, World!
  2. Getting to Know Arduino : Part 2 : Hello, Again!
  3. Getting to Know Arduino : Part 3 : Taking your Temperature

 

We want to make this space even better too and what we'd really like to know is:

  1. What else do you want to learn about Arduino?
  2. What can you teach others on the Community?

 

Let us know.

    In the simulation your LED's appear to *pop* if you draw too much current through them as well. image

    I am building an solar-powered arduino-based bluetooth weather station using Eagle.

    The firmware and corresponding android app are complete except for final debugging and tweaks. Now it is mainly waiting for hardware to show up, and building the housing....

    I've got a'back-burner Arduino project for a DMX 512 to  RS-232RS-232 gateway The idea originally was to convert DMX 512 commands from an industry standard lighting desk and turn them into  RS-232RS-232 commands to control a digital signage player interactively so that the lighting desk could select different content on the signage player as part of lighting scenes

     

    The electronics is pretty straightforward a MAX485 or similar on the DMX 512 side and a MAX232 on the  RS-232RS-232 side to convert the levels

     

    However the programming is slightly more tricky as unfortunately the DMX 512 timing doesn't play nicely with the USART.

     

    Most people appear to end up using a bodge by flipping the USART between two different BAUD rates as a work-around. One to handle the long start of transmission break and the other to handle the actual data.

     

    I don't really like relying on bodges but I've yet to see a tutorial where someone has come up with a  documented way to handle this sort of thing correctly. I was thinking about handling the break via a second tri-stated input/output and then the data via the USART at a fixed BAUD rate as a possible solution.

     

    Another project idea is a lower cost matrix display sign using the likes of pixel LED strips. There are plenty of projects and tutorials out there for driving small matrix LED's / 7-segment displays but I've not seen many tutorials on how to scale this up to larger dot matrix type displays that could be used in real-world scenarios. Perhaps using a number of Arduino powered display panels which could be connected together to build a scalable matrix display of X rows by Y columns.

     

    Perhaps something a bit like Google's AnyPixel.js project
