The circuit for the above layout is shown below:
Open the Amicus IDE and type in the following program, or copy and paste from here:
' Demonstrate a switch input using a pull-down resistor
' Display state of the input pin RB4 when a push-button switch is operated
'
Click the toolbar icon
Amicus18’s microcontroller.
Open the Serial Terminal by clicking on the toolbar, and open a connection to the Amicus18. Use the
default baud of 9600. The serial terminal’s window should show the text “Button = 0”. This is dis-
playing the state of the pin where the button is attached. Press the button and the test will change to
“Button = 1”:
