The setup() function is called once at the beginning to set the LED pin as an output. The loop() function contains the main logic and is executed repeatedly. Usage: Connect the positive leg (longer ...

Connect the common ground of the LED array to the GND pin of the Arduino Uno. Connect the positive terminal of each LED to a separate digital pin (0-7) on the Arduino Uno. Insert a 330 Ohm resistor in ...

Programming your Arduino: Now that our hardware is ready we can start programming our Arduino UNO board. The complete Arduino LED Blink Code given at the end of this page, further below we are just ...

In this project we are going to interface RGB (Red Green Blue) LED with Arduino Uno.A typical RGB LED is shown in below figure: The RGB LED will have four pins as shown in figure. PIN1: Color 1 ...

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 ...

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… ...

At its heart is an Arduino UNO, which syncs the RGB LED ‘bubbles’ and a servo-driven aiming arm to the game’s real-time data. A Lua script monitors MAME’s memory locations to match the ...

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.
