The DigitalOut widget sends values to hardware to set the output of a digital port to a HIGH or LOW value. This can turn on or off anything connected to the digital output port, for example an LED or relay.
Instructions
1 Connect
Connect another widget’s output to the input of DigitalOut.
To set the digital output port on your device, type in D plus the port number in the right hand tab. Be sure there are not other widgets connected to the same port.
2 Simulate
Even without another widget connected, you can simulate input values by moving the on-screen “knob” to send values out to your hardware. You may need to unclick the checkbox on the right or left of a widget if a device such as Arduino is not connected.
