Arduino – I Understand Arduino: Now What?

arduino

Alright, I've played around enough with Arduino that I feel pretty comfortable with it. Anything done now is more learning the electronics than it is the Arduino side of it.

What's the next step for my learning? Arduino is a combined programmer / controller, so presumably I need to break that link and start working with a controller chip separate from the controller, I guess? Can somebody point me in the right direction?

Here's some tips for working with AVRs and C.

Start off with embedded C with ATmega32 (ATmega AVR series)

void (*app_start)(void) = 0x0000;

This isn't a NULL pointer. This really is the address of the start of application code, which the bootloader jumps to. The linker arranges for your application code to start at address 0. See table 26-6 in the ATMEGA168 datasheet.

The bootloader code starts higher up in flash. Exactly where depends on the bootloader fuses.

You are going to want to use a linear regulator. This will be very inefficient with respect to power efficiency, but your arduino should not use much power and this should make the power point moot.

Here is an example search for the part you would need on mouser. If you are going to pull very much current you are going to need a heatsink, this would probably amount to anything greater than 100mA in your case(just a ballpark so you have a way to estimate your threshhold).

It will require a couple of capacitors, but any good datasheet will tell you exactly what components you need.
