Button Input Card provides two programmable push buttons for your project. They can be found on the back of the card. These buttons are large by comparing the standard pushbuttons and labelled as A and B.
Button is the most commonly used and intuitive way of signal input, which is widely used in our daily life, such as the button of remote control, the volume button of mobile phone, and doorbell on the door of Garden, etc. Even the clicks in computer interfaces are based on the prototype of buttons.
When using a button, there are two steps, pressing and releasing. Through combination, there can be single click, double click, long press and other operations. So that a button can achieve a variety of signal input. Buttons interact primarily through active presses, but can also monitor a variety of other behaviors, such as collisions.
In addition, the combination of the two buttons can also run the logical operator of “OR AND NOT”. Press either of the AB buttons to trigger the switch, which is the logic of “OR”. The switch can only be triggered when the two buttons are pressed at the same time, which is the logic of “AND”.
