SalMonDuino: A simpletest ATMega328 Arduino

This is a tutorial shows you how to build your own Arduino, I name it as SalMonDuino which is derive from my name (SM Ching). SalMonDuino is an modified version of original post written by Serisman, features include:

Using stripboard eliminate the trouble of drilling PCB holes
Simple circuit design uses minimum of components
Using 16MHz resonator as clock source
Prototype area

8 Channel Relay Box

This is a 8 channel relay box that the input connect to a controller allow it to control large loads like home appliances.

I'm using this relay box for a snooker centre to control snooker table lamps. The lamps consists of 6 pieces 20W and 3 pieces 10W fluorescent lamps, total of power consumption is 150W per table. Picture below shows the snooker table lights for the snooker centre.

Wireless Router Home Automation

This project eliminate the use of an expensive Wifi/Network Shield but still able to control home appliances from any where. You may already own a wireless router which support OpenWRT or else you can get a very cheap wireless router such as WR703N for this project.

In order to eliminate install many packages on the router, I am using HTML and Javascript for the web interface, while hardware interface is using Lua which is come with OpenWRT. The whole process is just install a serial driver (see step below) to make the instruction simple & keep the router free of resources.

16 Output Arduino Controller

The is a sketch for Arduino to communicate with computer or embedded device (eg. wireless router) using serial communication.

Arduino Duemilanove have 14 digital IO pins (2 digital IO used by serial) and 6 analog IO pins. Here I coded the analog IO as digital IO, so we can easily get 16 digital IO.
