A component in the electronics kit that can be used to give an input to your pi. The button has 4 legs and should straddle the middle trench/valley up the middle of the breadboard. Both of the “lower” legs should be connected to a 10K ohm resistor. One of those resistors should then run to ground from each button via a wire, and the other resistor should be connected to a pin to power the button (one of the 3.3v pins) via a wire. Then the “upper” left left leg of the button should be grounded. You must then set the connected gpio pins to “input” mode. When everything is connected and powered, the button should read as a “0” when it is not being pressed, but then becomes a “1” when it is being pressed. You can check this by running “gpio readall” while the button is not being pressed, then again while the button is being held down. You should notice the “0” change into a “1” in the displayed table.

A conditional statement in computer programming that allows you to perform 2 different blocks of code depending on whether or not the given condition is met. The condition is a simple as

   if (condition == 1){  //checks to see if the condition is true (true = 1 in programming)
      Code to be executed   //This code will be executed if the condition is met 
      }
      
   else{                 //If the initial condition is not met/is false
       alternative block of code to be executed  //Code to be executed if the condition is not met
       }
