Examples

Here is an example Flowcode program to read the values of a switch array. Switch Array

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

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

Property reference

	Properties
	Switch Settings
	Count
The number of LEDs in the array from 1 to 8.
	Input Mode
Choose a single port for all LEDs - pins are allocated in sequence from pin 0 - 7 ...or choose 'Custom pins' to assign each switch individually.
	Port
	Polarity
Active High = LEDs light when the chosen chip pin is ON Active Low = LEDs light when the chosen chip pin is OFF
	Debounce
Time in milliseconds allowed for the pin to settle following a change of state.
	Operation
Sets whether switches toggle or are press/release. NB) This option can only be set when the original target includes this option.
