Since it's using the internal pullup resistors, no external ones are needed. The one minor issue is that it inverts the state of the buttons -- 0==pressed, 1==released (not pressed).

WebJun 6, 2024 · If you use an array for your buttons, you can still use names. #define BUTTON1 0 #define BUTTON2 1 #define BUTTON3 2 const byte bts [] = {5, 6, 7}; bool btgs [3] = {false, false, false}; The first part defines names; each name is an index in your array. So to read the second button, you can use e.g. if (digitalRead (bts [BUTTON2]) == HIGH) WebAdd a black wire between a GND pin of the Arduino and the “-” (minus) line of the breadboard, as to create a common ground in the breadboard. This will make things easier when you add more components. For each LED: Connect the shorter leg to the ground (the minus line on the breadboard). Connect the longer leg to a digital pin – doesn’t ...
WebLets first look at how you would normally read a button. In its simplest form, you would connect your button like the circuit shown. As you can see, you need 1 Input pin and 1 resistor per button, and then you can check the state in your Arduino sketch using this: buttonState = digitalRead (buttonPin); I'm not showing all the setup etc...
