Get an mbed!
When you signup with an mbed Microcontroller, you get an account and access to the online compiler. If you have an mbed Microcontroller already, Login or Signup!
The mbed Compiler lets you write programs in C/C++, and then compile and download them to run on the mbed Microcontroller.
It's all online, so you don't need to be a sys-admin to start. Infact, you don't have to install or setup anything to get started
Your workspace is also in the cloud, so you can login from anywhere and carry on where you left off.
And because it is a web app, we don't care if you work on Windows, Mac or Linux. Or all three.
