Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

Arduino UNO 2. Push Button 3. LED 4. 220 ohm resistor ( for the LED ) 5. Breadboard Usually we need a resistor for the push button. However, since the Arduino UNO has a pull-up resistor built into it, ...

This project demonstrates how to control an LED using a push button with an Arduino board. When the button is pressed, the LED toggles on and off. This simple circuit can be a great starting point for ...

Once we have successfully uploaded the code to the Arduino board it is time to verify the output of our program. The hardware connection of my Arduino is shown below, to verify the output all we have ...

PIC, AVR, and Arduino are ubiquitous in projects these days and a lot of the time it’s easy to over-complicate things with their use. In this case, [Tod] wanted to use a momentary tactile swi… ...

So if one push button is pushed then the corresponding LED should glow for 2 seconds, similarly if second is pushed then LED should glow for 4 seconds. But when we use delay(), if the user is pressing ...

The decimal number increases from 0 to 255 each time the momentary push-button is pressed. For example the number 0 is 00000000 in binary so no leds must be ON, number 1 is 00000001 so only the ...

An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off. Instead of adding a button for “push to start” he opted for a 13.56MHz RFID module.
