//configure pin2 as an input and enable the internal pull-up resistor pinMode(2, INPUT_PULLUP); pinMode(13, OUTPUT); } void loop() { //read the pushbutton value into a variable int sensorVal = digitalRead(2); //print out the value of the pushbutton Serial.println(sensorVal); //...
Now that your setup has been completed, move into the main loop of your code. When your button is not pressed, the internal pull-up resistor connects to 5 volts. This causes the Arduino to report "1" or HIGH. When the button is pressed, the Arduino pin is pulled to ground, causing ...
Pull up resistor Instead of using the internal pull up resistor from your Arduino board, you could decide to create the circuit yourself and add an external pull up resistor. Your circuit will look like this. Here I have simply added a 10k Ohm resistor between one leg of the button (same...

This is a harder pill to swallow but it’s a necessary evil. For this to work the Arduino board emulates an Xbox 360 wired controller, which means it also borrows the use of Microsoft’s USB VID and PID so that the Windows driver will pick it up. Without this VID/PID combination the...
Snap4Arduino is a derivative of Snap!, and is thus also free software released under the AGPL, which is a CopyLeft license. There are different points of view on whether screenshots are derivative works or not, but the practical answer is that nobody will ever come after you for using a...
A simple Arduino library to make interfacing and reacting on button events easier. Overview: Features This library supports: Push buttons (with or without pullup or inverted logic) On/Off Switches Rotary Encoders TheLameboy:D Any Analog input (i.e. ButtonMatrix) ...
Next up is the setup() function. Here we’ll initialize the pins we’re using, set the input range for the joystick (potentiometer), and ‘begin’ the library: void setup() { // Set input pin modes pinMode(Pin_ButtonA, INPUT_PULLUP); pinMode(Pin_TriggerR, INPUT_PULLUP); // Set...
