==Switch Array (Slide) component==
An array of up to eight slide switches. In embedded mode each switch is connected to a single pin of the specified port.

==Version information==

 Library Version, Component Version, Date, Author, Info
 10, 10.0, 26-06-24, MW, Corrected switch and component name bug
 12, 11.0, 16-04-25, MW, Corrected bug when sim stopped Switch changed from on to off, but pin remained at VCC
 12, 11.0, 16-04-25, MW, Added properties of Ev_PropertiesEX to Ev_Initialise
 12, 11.0, 16-04-25, MW, Fixed bug so individual customisation now works

==Examples==

Here is an example Flowcode program to read the values of a switch array. 
{{Fcfile|Switch Array.fcfx|Switch Array}}

Here is a schematic of how to connect a basic switch to a microcontroller pin.

[[File:switchschematic.jpg]]

The active high circuit will pass a logical 0 to the input pin when the switch is not pressed and a logical 1 when the switch is pressed.

The active low circuit will pass a logical 1 to the input pin when the switch is not pressed and a logical 0 when the switch is pressed.


There are some differences depending on the type of switch you have, the above states assume a generic push to make type switch, however a push to break type switch would have reversed logic and a toggle switch can work well with either setup.


The resistors are required for correct operation because when a microcontroller's input pin is essentially connected to nothing it will pick up noise in the environment and provide inconsistent readings. This state is referred to as floating i.e. the pin is floating. To test this remove the resistors (if possible) and touch the unconnected pin with your finger the output LED from the example file above will toggle on and off at high speed.


Any values of resistor can be used but it is important to keep the smaller resistor at least 10X smaller then the larger resistor to ensure that the pressed state provides at least 0.91% of the required pressed state voltage. For example a active high switch circuit using 1K and 10K resistors should pull up to about 4.54V when the switch is pressed.

(5V / 11K) * 10K = 4.54545V
