# How To Program Your Micro-Controller
This is about using `avr-dude`, `make` and getting a high-level understanding of what's happening under the hood so that you can tune your micro-controller yourself.
In practice, you can just read most of what is linked in the **Embedded Programming** class [there](http://academy.cba.mit.edu/classes/embedded_programming/index.html).
In fact, you should have done that already.
But for those who are overwhelmed, we will try to disect some of the content

## What are those files?
For most base projects of HTMAA, you are provided with a set of different files:
* `file.png` are typically images for tracing (trace) or cutting (outline)
* `file.c` is a C file that contains a C program, which runs on a micro-controller
* `file.make` (or anything ending in `.make`, so here typically `file.c.make` too) is to use the program `make` to call commands that allow you to do things
## What does `XXX` do?
First thing first, you should try reading the manual.
On Mac / Linux, you can access the manual of a specific command typically by typing
```bash
man fancycommand
```
## What is [Make](https://www.gnu.org/software/make/manual/html_node/Introduction.html#Introduction)
