16.0. Push Buttons
16.0. Push Buttons
The logic state of all microcontroller input pins may be changed by means of push buttons. Jumper J12 is used to determine the logic
state to be applied to the desired microcontroller pin by pressing appropriate push button. The function of the protective resistor is to limit
the maximum current, thus preventing a short circuit from occuring. If needed, advanced users may shorten such resistor using jumper
J13. Right next to the push buttons, there is a RESET button connected to the MCLR pin over the on-board programmer.
By pressing any push button when jumper J12 is in the VCC position, a logic one (3.3V) will be applied to the appropriate microcontroller
pin as shown in Figure 16-2.
