Digital Sensors

You can also add additional sensors or switches to your CBC, and you plug them into the slots labeled “digital.”

In C you call them by digital(x); where x is the number of the digital sensor port (8-15), and the function will return a value of 1 if the sensor is activated or a 0 if it is not.

An example of a a digital sensor is a switch or a button. Such as used in bumper sensors. Digital sensors either are yes or no, and nowhere in between. It’s black and white. For the gray in between – go to the next lesson: analog sensors.
