1). When the Arduino board is connected to your PC, open “Control panel” and click on “Hardware and Sound”. Then click on “Devices and Printers”. Find the name of the port to which your Arduino board ...

Upload the Arduino sketch using the Arduino IDE. Power the Arduino using a USB cable or external power. Press each button to control its corresponding LED. 📌 Notes. Ensure that the resistors are ...

This project controls a relay module using an Arduino, providing both automated timer-based operation and manual override functionality via a button. The system is designed for applications where a ...

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 ...

How do you turn an LED on and off with a button on Arduino? We set the pinButton variable as integer 8 and we connect the button at pin 8 on the Board. Then the LED is connected to pin 2 using the ...

In our hardware the push button is input which is connected to the second pin of the Arduino. If you take a close look you can notice that one side of the button is connected to the Ground and the ...

Step 2: Connect LED Light Strips to the Arduino. Now that you have all the necessary parts, it’s time to connect the LED light strips to the Arduino. The first step is to identify positive (+) and ...

Upload this code into the Arduino connected to the master HC05 module first. After uploading the code, plug out the Arduino power cable. Press and hold the button on the HC05. Now plug in the Arduino ...

A light meter is a very useful device that finds applications in hospitals, schools, factories, parking lots, passageways, and many more to measure and maintain adequate lighting levels. It is also ...

The circuit of Arduino-based shadow alarm is shown in Fig. 1. It consists of an Arduino board, power supply, light-dependent resistor (LDR) sensor, buzzer, relay driver and a few other components.
