Once you understand those two concepts you can start to write useful programs. The two most important concepts in programming are conditional execution (if statements, etc.) and loops (doing something over-and-over, usually until some condition is reached). But, I haven't really thought-through your program. The constructor defaults to INPUTPULLUP which may (or may not) be what you want for your buttons and toggle switches, so it's something to bear in mind especially for low-side push-to-break buttons or high-side push-to-make buttons which will generate rising edges when pressed and falling edges when released thus reversing the meanings of. When the button is pushed, the loop ends, and you go-on from there. After the buzzer is turned-on, you enter a while() loop and you just stay in that loop (doing nothing) "while" the button is not pushed. The circuit ensures that the digital input pin we declare and use as the interrupt pin is maintained at 0v when the switch is open (off), thereby removing spurious inputs arising from. This is a very common way to wire up a simple switch circuit. This example turns on the built-in LED on pin 13 when you press the button. Button circuit - The button switch circuit is configured as per Figure 1 (Circuit 1), below. There are for-loops (the most common type of loop), do-while loops, and while() loops. Pushbuttons or switches connect two points in a circuit when you press them. Connect the other corresponding terminal to Gnd. By combining a microcontroller (with its. Step 3: Put the resistor with one end in +5 V and the other end connected with one of the terminals of the switch. Arduino Toggle Switch: How to make one without having one A toggle switch is simply a push button switch with memory. You can add more loops inside the main loop (and you can make more nested loops). Put the switch in the breadboard and put an LED with the longer end into pin 13 and shorter end to the Gnd of the Arduino. And, you should think about what happens next, after you push the button and the buzzer stops. So, you'll need to make sure the program doesn't loop-around and immediately turn the buzzer back on after you push the button to stop it. Remember that your program ("sketch") runs in a loop. Turn on and have a switch button turn it off. Take a look at the Button Example to get an idea how to read a button, and then "do something" based on the button state. You may also need some 'and' or 'or' logic.
