Easy to use Arduino Shield for smart Robotics projects with Lego EV3 /NXT sensors and motors. Use this shield in Arduino IDE with C++.
if you are looking to do a “Internet-of-Things” project with students, this is a good place to start.
Ardublock is a graphical programming environment to make programming physical computing with Arduino as easy as drag and drop.
The MicroView is the first chip-sized Arduino compatible that lets you see what your Arduino is thinking using a built-in OLED display. Looks great for education.
When working on Arduino projects, you have to explain circuits. This is a very nice, simple simulator for that!
With 123D Circuits you can design in a familiar breadboard view and the app will guide you to make professional printed circuit boards with built in layout tools. When you’re done just click to have your boards professionally manufactured and shipped for free worldwide.
What’s also cool is how you can easily, simultaneously work on the same circuit with your friends. And at any point you can compile and emulate your Arduino code inside a live, editable circuit!
A nice animated and interactive lesson on using Arduinos ! You do have to install the Unity3D web player however to use it.
Here is the description of this series of Web pages. I bolded the part that was of interest to me !
Do you have a bricked Arduino that won’t accept code anymore? Or, maybe you wrote your own firmware and would like to upload it to your Arduino? Or, maybe you just want to learn more about the inner-workings of Arduino, AVR, and microcontrollers in general. Well, you’re in luck! This tutorial will teach you what a bootloader is, why you would need to install/reinstall it, and go over the process of doing so.
This is a great site with a lot of hardware lessons based on using Arduinos mostly.
As a follow on to the previous post, here is another video from Jeri Ellsworth on the need to fail and fail often.
