Uploading the Arduino LED Blink Code. Now, let’s upload our first program to the Arduino board through the Arduino IDE that we just downloaded. The Arduino IDE when installed comes with some example ...

This project turns an LED on and off using a push-button connected to the Elegoo Uno R3 (Arduino-compatible). It demonstrates basic embedded system control logic — a core principle behind CPS and ...

This project is built using PlatformIO. The code is structured to separate hardware interactions from the core logic, making it testable without actual Arduino hardware ...

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 ...

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor ...

Connect it to a 12 V power supply, download a program (Check the full code below) on the Arduino Nano and run it. Press the button to switch flash mode. If you want, you can clone my LED Scroll Bar ...

When you read “Arduino wristwatch”, you fall into the trap of envisioning an Arduino UNO clumsily strapped to someone’s wrist. [Marijo Blažević’s] creation is much more poli… ...
