Digital Input Agent

Use the Digital Input Agent to get a digital signal from the outside world and make it available to the rest of your application. Set a Digital Input to a pin on the microcontroller that is connected to a digital sensor or other digital device. When the Digital Input is connected to a device through the pin, its value becomes the same as the device's. Read the Digital Input to get the value of the device.

Use an Event Component to detect these self-explanatory events from the Digital Input:

Detect these Analog Input Agent events using the Event Component:

• Goes On
• Goes Off

Digital Output Agent

Use the Digital Output Agent to produce a digital signal from your microcontroller. Like the Digital Input, you attach the Digital Output to a pin that is connected to a digital device such as a switch. When your application changes the value of the Digital Output, the Digital Output will flip the switch accordingly.

Use an Event Component to detect these events from the Digital Output:

• Goes On
• Goes Off

The Digital Output can perform these Jobs:

• Set to: An assignment Job, the Digital Output's value will become the value specified.
• Toggle: The Digital Output Agent will switch states (if it's ON, it'll turn OFF; if it's OFF, it'll turn ON).

Digital Variable

The Digital Variable Component is used to store a digital value. Set the value manually using a Visual Control such as a Switch or periodically sample value from any other Digital Component source.

Create "smart-switch" behavior by adding a delay before the Digital Variable changes state simply by checking a checkbox and setting the length of the delay.

Use an Event Component to detect these events from the Digital Variable:

• Goes On
• Goes Off

The Digital Variable can perform these Jobs:

• Set to: An assignment Job, the Digital Variable's value will become the value specified.
• Toggle: The Digital Variable will switch states (if it's ON, it'll turn OFF; if it's OFF, it'll turn ON).

Digital Operator

The Digital Operator Component is used to perform Boolean operations on any two Digital Components. The state of the Digital Operator is the output of the operation. Create state logic using Digital Operator Components: If the valve is closed AND the switch is off, shut down the pump, for example.

Select any of the following operations: AND, OR, XOR, NOR, and NAND. Invert either of the operands simply by clicking a check box.

Use an Event Component to detect these events from the Digital Operator:

• Goes On
• Goes Off
