Server Load

The actual calculation for server load is a little bit complex, but for basic understanding, it can be simplified. The best way to think about server load is that it is the average number of processes that are currently running (or waiting to run) in the given interval. Traditionally, server load is given in blocks of three – one minute, five minutes, and fifteen minutes. Load can be caused for many reasons – actual CPU time, waiting on network buffers, waiting on the disk, and on and on. Continue reading Server Load

Arduino.INO

This code is the code that is put on to the Arduino, you can modify the pins based on your board and if your board supports PWM. most should be able to do this. This program also accepts the data that is sent by the Arduino.exe program that was built from the Arduino.cpp. That receives the data from the Arduino.php.

Arduino Home Automation

So I have been planning on creating a web controlled interface to control the lights, fans, thermostat, ambient lighting, door locks, garage door, and many many other appliances from the convenience of a website, an app, or a button. My old system used to be called A.D.A.M: Automated Defense and Management. Now I believe a re-branding is in order, Simply put A-HA! Arduino Home Automation.

Arduino Relay Control

I purchased the SainSmart 16 relay board to control up to 16 devices or wall sockets. The Uno has 14 Digital pin outs, If I want to expand I will need to use a multiplexer to increase the amount of pin available. I have used a Texas Instruments TLC5940NT. You can request a sample if you want to “Test” small scale here’s how:

Here is some of the code to help with expanding the number of pins.

Here is a video of what the end result should look like with various components attached.
