Arduino (C program)

Create 3 functions which match the following types:

A) Simple value dependent decision statement // Reference > Language > Structure > Control structure

Compare value, of the ANALOG pin to some value [in range of the ADC (8bit)]. This function should set a DIGITAL pin [any pin other than the pin you've slected to read from] either HIGH or LOW based on the value of your chosen pin at the start of each loop(). This function should also set (assign or change the value of) a GLOBAL variable of type BOOLEAN (TRUE or FALSE).
