-#ATmega 328p / Arduino over SPI
-
-###Did you know that your Pi could power and program an ATmega 328p/Arduino directly, with nothing but a few wires, a breadboard, a 16Mhz crystal oscillator and some 22pF capacitors?
-
-Read my [complete Pico PiDuino tutorial](http://pi.gadgetoid.com/article/building-the-pico-piduino) to get started for just over &pound;5
-
-You'll need to install [Gordon Henderson's modified AVRDude](https://projects.drogon.net/raspberry-pi/gertboard/arduino-ide-installation-isp/).
-
-Connect 8/CEO to your ATmega's Reset/RST pin, 9/MISO to its MISO pin (D12), 10 to its MOSI pin (D11) and 11/SCLK to its SCLK pin (D13).
-
-Power your ATmega with the 3.3v and GND pins from your Pi, and you're good to go.
-
-Make sure you have no rogue SPI device drivers running and check it's connected correctly using:
-
-```bash
-avrdude -p m328p -c gpio
-```
-
-To get started compiling Arduino sketches from the command line:
-
-```bash
-sudo apt-get install arduino arduino-mk
-```
-
-This basic Makefile should get you started. Create a basic sketch, name it mysketch.ino and run:
-
-```bash
-export BOARD=atmega328
-make
-avrdude -p m328p -c gpio -e -U flash:w:build-cli/Arduino.hex
-```
