Using a button to toggle an LED on the Arduino is a logic game. Our sketch will monitor the button to see if it is pressed, or not pressed. On press, the LED will then toggle On or Off, depending on what state it is currently in. If the LED is on, it will turn off. If it...
And then we’ll modify the program to toggle the LED’s state only when we release the button. For more info on each component, also check out thisArduino LED tutorialand thisArduino push button tutorial. Let’s get started! >> Watch this video as an additional resource: You are learning...

Before soldering, doublecheck the alignment of the flat side of the LED. When you're sure it's the right way around, solder it down, and snip the leads. Wires For the following exercises, we'll simply be using solid-core wire to connect the keypad to the Arduino Mega. If you've go...
Step 1. Open the Arduino IDE and create a new file, then copy the following code into the new file. #include "Arduino.h"//1: toggle mode, 2: follow mode#define LED_MODE 1const int ledPin = 3; // the number of the LED pin, D3const int buttonPin = 4; // the number of the...
