Minimal Arduino-compatible circuit with ATMega328

(Hack a Day) ... It’s a very, very minimal Arduino-compatible circuit meant to control all the pins on an ATMega328. The components only cost about £1.40 ($2.25 USD) when bought in volume, making it perfect for teaching a class or workshop on the Arduino and giving each student a circuit to take home.

The basic circuit is just an ATMega328 – the same microcontroller used in the Arduino Uno – with a few caps, resistors, and a 16 MHz crystal. It’s a very bare-bones system, but once built and programmed provides all the functionality of a $25 Arduino.

Like all microcontroller platforms, there’s the chicken-and-egg problem of actually programming the device. The Shrimp team is using a CP2102 USB to UART bridge to program each shrimp. Not an inexpensive part, but it is of course possible to only have one serial bridge for each workshop.

    note: get MCs with Arduino bootloader preloaded,
    like this https://www.sparkfun.com/products/10524
    or the ones at shrimping.it

    also there is this stuff:
    USBaspLoader is a USB boot loader for AVR microcontrollers. Instead of requiring a separate downloader tool on the host, it emulates the popular USBasp programmer so that it can be controlled by AVRDUDE.
