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, ...

⚠️ Important: Ensure that all ground connections are properly linked to the Arduino GND pin to maintain a common ground across the circuit.. 🎯 Project Behavior Once powered and programmed, the three ...

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 ...

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

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 ...

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.

An Arduino is a small, programmable device that can take inputs (in this case, two buttons) and control outputs (a LED screen to show the score). The Arduino, and the components we used ...
