I am planning to use the broard to periodically operate a manual button of my digital protractor. The board of the device works on a 3V battery. The button to be operated on is for changing the unit of the angle displayed by the device. It has two connections. #1 is connected to the ground ( -ve pole of the battery ) and #2 to an input of the circuit of the device. I am wondering if I can connect one of the digital output pins of Seeeduino Xiao directly to connection #2 to operate the button. Thanks in adance.
I'm new to this, but you should be able to set the pin to high and ground it out through the button so that it reads low when pressed. Kind of like the opposite of the button in this: https://www.arduino.cc/en/Tutorial/BuiltInExamples/Button.
