IDIOT-PHP-DEVELOPERS - Fix mysql_connect etc. deprecated (with mysqli_connect and so-on..)
<?php
// include file for php called "IDIOT-PHP-DEVELOPERS"
// this file is a dirty fix to fix deprecated mysql_ - functions.
// first of all, I really don't understand why these functions needed to be deprecated.
// this decision by PHP developer has caused hundreds or thousands work hours to fix
// about this "library" : it might have not all functions so feel free to continue this work

//ATmega328P sleep demo
//
//Wire the usual Arduino LED from PB5 (DIP pin 19, Arduino pin 13) to ground, through
//an appropriate current-limiting resistor.
//Wire a tactile button switch from INT0/PD2 (DIP pin 4, Arduino pin 2) to ground.
//
//The sketch will blink the LED three times, then go to sleep.

// www.electrosmash.com/pedalshield
// sinewave.ino program creates a sinusoidal waveform adjustable in amplitude and frequency.
// potentiometer 0 controls the frequency.
// potentiometer 2 controls the amplitude.
// VERSION HISTORY:
// 5.1.2014 - j0uni : This version uses bitwise AND to get the "rolling" pointer to sinewave table.
